Okay, here's the deal, it's gonna take alot more than 5 minutes in MS Paint to make a decent character sprite. The black outline is icky looking, and unnecessary, as well as jutting out further than it should in several places. The character itself is undetailed and disproportionate. And oh yeah, it's unshaded.
Sorry, but it's gonna take alot more work than that before you can get a halfway decent character sprite.
