Yo!
Sorry, but I'm going to admit that these are pretty horrible. I don't understand the 52 days deadline, it seems rather arbirtrary?
Anyway, onto your sprites.

Your sprites fit roughly in a 48x48 canvas. The TFR maximum is 64x64, so your sprite is about 2/3 of the size of most of the other sprites. I suggest you put your sprites in 64x64 sized frames for scale, so that you know whether you're working too big or too small, if you still have room or not, etc.
I would then make your sprite a bit bigger.
After that, I suggest that you look at some sprites of fighting games you know or like, or characters that could help you make your own. If it helps, you can stick them next to your WIP so that you can look at them whilst working.
So there. Add what Iocus has pointed out and you should end up with a decent sprite.

Here's my edit, with a few palette swaps:

Hope it helps.
