Hello pixel artists, first post here so I hope i'm not breaking any rules.
Anyway currently my main character is a square with a line on it

. I've been trashing designs for weeks now and I think I have something that might work.
I think the chest needs a little work. Perspective seems off a little and the shading/non existent AA
I need the color count to be low enough so animation is a reasonable feat.
As you can see the character kind of strangely proportioned (short and wide)
but things would work out best if the collision on the character was squarish and less than 32x32.
The game is a time trial type game and the character can achieve high speeds, so I need it's design to reflect that.
I need to get the look of it down before I start on animation so, if anything immediately sticks out as bad please let me know.

Here she is against some different colors

Thanks for reading!
