Spriting:
I spent a good long time doing this template but after a little while and alot of sprite observation I've come to think something is wrong with the design of these sprites, I need to know what's wrong with them though, I think it's something with the shape and what not, I don't know, maybe someone could lend me a hand?

I'm relatively new posting here, but I've been around for a while, after lurking for so long I decided to make an account.. Definatley need some critique.
