Thanks a bunch for the feedback. I'll answer 1 thing at a time
Colors:
I do plan on adding more colors. Probably some yellow like you suggested and maybe some bright reds. I do need something besides the dark blue and red purple-ish body suit color. Since I painted most things on a single layer, changing the colors will be a bit tricky but I will try. Hopefully some time next week I'll have a new update.
As far as her powers go...well lets start with the wings. The wings are like a car exhaust so there's energy coming out of the Wings and she can control that energy to shot energy beams or make planet size balls of energy to defeat her enemies. (This is my version)
But this is a story element in the piece that I actually enjoy hearing different opinions on. To my some of my friends, it gives a nostalgic feeling. Other think the wing part is projecting plasma energy so she can potential fly. There were other things but I forgot them.
Being too in front was kinda an aesthetic choice. I can try making the canvas more wide. I'll try to work on the shoe thing as some things aren't final yet.
Thanks a bunch for the feedback. I'll probably post this on some other social groups and try to see what others think. I totally know what you mean about having to much feedback.
