My guy you can literally use MSpaint and circle tool and eraser to clear some lines to make a guy. I conceptualized and drew this in like 5 minutes. Some angel platformer fighter character. I imagine the bandana flowing and trailing behind the character as they jump. Could probably use the halo as a weapon or something. The hardest part was the bandana which was the only part I did free hand. This is obviously a first draft concept art and needs to be seriously polished and prepped for animation, but in the second picture I shrunk it down to 64x64 and a lot of the flaws disappear. You just need to learn some technical stuff about composition and color theory to make something that's even half decent and it will be enough. Or hell, literally steal this character idea because I'm not doing anything with it. Here's you're written permission.
Make a cool game and put MSpaint art in it! (but actually use a better program because MSPaint kinda sucks.)
I'm just showing you there's ways around limitations.
