you should make a hybrid power fight, each person has 2 powers. (like gold alloy or copper manipulation paired with electricity can make magnets from coiled wire, or highly conductive accelerators idk xd)
learning better anatomy is also super helpful for skill, using references for a long while just drawing anime characters and backgrounds will give you a sense of direction after awhile. just have fun when you draw, and when you get a better flow with a small line width, try learning anatomy from a youtuber that actually tells you how to build, like 'chommang drawing'. Not 'draw like a sir' or any vtubers you see out there, they are not helpful tutorial artists and are generally too young to be giving advice in the first place if they can't describe what they do naturally.
as for art, I usually use a reference if its supposed to be realistic. I start with a super rough sketch with 1pt lines, then I make a new frame and make generic solid color shapes, then I shade and make the lines using colors if I want. For a more realistic effect (especially for shading/glowing) you can use low opacity and run over it like 20 times over to get a really smooth blend I guess you could call it
maybe you're not interacting with the community lately, most people who are the most loved are either art geniuses or just talk a lot. being yourself and saying what you think should get you in enough comment sections
