I like the big fists

I think the legs are pretty solid, all you need is clean up my man. The exaggeration is perfectly fitting, and as other people below said, your work would fit a game easily. My only issue is this is basically Miss Fortune from Skullgirls, fused with robo Fortune, but honestly that's not a bad thing.
I say don't knock yourself too hard with it, do something with what you got.

Hope ur braincells recover lol
the design and silhouette is great
the tail doesn't really stand out though. either remove entirely or iterate/change tail design

You ever thought about hitting up a programmer and making your own fighting game. You definitely have the sprites down and the style alone would draw in some folks.

This is pretty fantastic work! It has some good detail, and it's kick-ass as much as it is cute and sexy!

Very cool work! I look forward to the finished design.
