I like it, save for the black outlines inside, the same effect could be achieved with shading.

His stance looks like he'll topple over to the left, so I suggest moving his right foot (not leg) a bit more to his right.
The aa on the outline seems to have made almost no difference, as it still looks jaggy.

I really like that scythe. Not the shine, but the scythe head itself. And the overall design is pretty cool too.
