I'm not a fan of 'chibi' (assuming that's what you categorize it as) but I'll critique it anyway.
Also assuming all of this wasn't intentional, you should fix the shine in the hair, it curves downward about halfway. The belt goes downward on oneside and upward on the other. There doesn't seem to be any mouth, and isn't 5'9" a bit much for the scythe blade.
Otherwise, it's good.
I like the wings! ^.^ so cute
