I'm working on kitties for a 2d game, looking for critique, especially on animation.

Here's my first revision:

And the second:


Working with flats for now until the animation is closer to final. Right now it's 7 colors.
Added a squash pose for each step and got the tail arc working better. Suggestions/drawover on the tail would be appreciated, I'm going for a tail that gets a bit thicker towards the second half, but it isn't really working out like that.
New to pixelation, I've pixeled before, but this is my first animation. Thanks for reading
