Ah yes I'll remove the dark spots that appear randomly.

I'm not gonna change the cape however, I hate to animate the cape again XD

Thx for the feedback!

The torso's movement is a little stiff, and I feel like the cape should wave out a little bit, it looks kinda wierd.

the arms are really dangly but that could be on purpose, it doesn't necessarily look bad.
There are a lot of little spots where I think you shaded the cloth (elbow, knee, hip) that just look wierd in the animation; like little blips of dark color. I would suggest taking them out or using another, lighter shade color so it isn't so jarring.

I like the character! The sprite itself looks great, but if I were you I'd touch up the animation just a little
