I'm a first-time spriter, and need criticism. Here's a sprite sheet of mine.

remember, pixelart is not directly about using pixels to make small-ass images of some character, it's using them to represent characters and their poses the best you can. This is called "Readability."

the main problem with these is that they don't change perspective in animations and thus they look pretty odd and lazy. Never cut corners when doing an animation like this, use your space to the fullest to represent what youre trying to convey.
