I always thought that Bloom's wings in her magic winx form looked like butterfly wings. It might be a bit of a stretch, but that's what I've always interpreted them to be.
Right before she gets her fairy form she (and the rest of the winx) perform a spell that restores the butterflies to those weird eggs that the specialists thought was a good gift idea.
I guess what I'm trying to say is that the actions and spells of a fairy before they unlock their fairy form determines what it is going to look like. The Magic winx form isn't predetermined. The fairy's actions shape them.
Going deeper here you could think more about the other girl's magic winx forms. Maybe Flora primarily worked with spells relating to flowers, which is why her magic winx form is primarily flower themed even though she is the fairy of nature as a whole. Maybe Stella used some spells that had to do with the number three or she saved three of something and that is why her wings are in three segments. Tecna saved someone from a hang gliding accident I have nothing for the other girls.
How their goals/lives would have changed without each other. Like if the other two never existed
Icy: For Icy not much would be different. She would still try to get the dragon flame and take over the dimension. I can see her being much more ruthless and bloodthirsty without her sisters. She would be more risky too, since she is only putting herself at risk. I don't think her story would really change until season 3, since Icy would not be competing for attention the same way.
Darcy: I don't think Darcy would be ambitious enough to try to take the dragon flame. I still think she would be manipulative, but she doesn't have any real motivation. She would still go after Riven, but eventually one of them would break it off and she would move on to the next man. This would create a cycle for her where she can't tell if she actually likes someone or if she just wants to manipulate them. Anyway. Angst.
Stormy: Without her sisters to guide her, I just imagine Stormy becoming a background character. She would still have anger issues, but I think without two strong personalities guiding her she would have a normal witch life. She wouldn't do anything remarkable, she would just be ordinary. She would be happier being normal.
You forgot this one
And more wholesome
Icy won't acknowledge this but she is the mom of the group. She is the one Darcy and Stormy come to with their problems for her to fix.
She is also the healer of the group and uses her ice to treat injuries. I recently watched the 4kids dub for the first time and in the "crappy pixies beating the trix via the power of having the same proportions as a funko pop" episode, Stormy calls the ice put on her eyes "the soothing ice," which I am choosing to interpret as this is something that Icy does often for her sisters
What do they think of the nickname "the trix"?
Icy: Icy loves it. She is proud that she and her sisters are so intimidating they were given a name that strikes fear into the hearts of others. Definitely one of her proudest achievements. Also her only real achievement
Darcy: She thinks it is an incredibly stupid name and is low key embarrassed that no one could think of anything better. And that was before she found out it was the name of a cereal. That was a depressing day for her
Stormy: Doesn't really think about it. She probably doesn't know that other people made it up. She just assumed that Icy made it up to seem cool (because she would)

I wrote my first winx club fanfic. (of the trix of course) Check it out if you want. I tried
Greatest fears (or one of them)
Icy: Her greatest fear is loss of power. She can deal with failure and rejection (she is used to it by now), but she would not be able to cope with loss of power. Not only her magic powers, but the power she has over others. She needs her sisters to be looking up to her. She needs to be the leader.
Darcy: Darcy would be most scared of loss of control. Darcy is a strategist and plans everything out beforehand. She is very conscious of everything she does and not having control would be stressful and demeaning for her
Stormy: Stormy would be most scared of getting left behind. She is scared of her sisters abandoning her because they see her as stupid and impulsive. She is scared to do things by herself and figure out how to live independently. She has major FOMO
Stormy and Darcy truly are an ADHD and Autism match made in hell
Quirks of our Trix. Because being weird about certain things is simply normal.
Icy hates mess. She hates dirt, dust just anything that ruins her perfect room interior. Everything needs to be put in one specific place. It's non negotiable. The place has been designated due to its design and practicality and all of you just don't understand. She has tendency of repeating things and redoing something if it doesn't matches her vision. Don't you fucking dare leave crumbs somewhere. Death sentence.
Darcy is sensitive to noise. She definitely has misophonia. Chewing, eating, ASMR it is just awful. She hates people shouting or screaming for no reason. She will wake up as a result of not fully turned off water faucet. Each drop driving her to her limits. She won't admit to stimming. Her legs shaking, moving up and down and her picking off her nail polish and playing with her bracelets is...just a nervous tic. Yes.
Stormy hates silence. Headphones took permanent residence in her ears. So does movement. She love spinning, dancing or just running down the corridor. Trips on hover bike are fucking the best. Witch of tornadoes once again reunited with the wind thanks to her 'I-don't-avoid-dsicussing-my-feelings sister'. If met with silence will just start signing or screaming. She will randomly broke into a song or some vine or meme.
Each girl's favorite scents
Icy: One of those perfumes that "smells" like bamboo, when it really smells like flowers. I can see. her liking a soft, delicate scent
Darcy: Lavender. It's a nice relaxing scent. Also purple. The plant being purple definitely played a part in making it her favorite
Stormy: The smell it makes when it's raining outside. (I'm low on creativity today, sue me) It is actually called petrichor, but Stormy would not know that
