I think it looks finished now myself, but I think maybe the cloth would be better if it were wrapped around the staff part of the scythe tightly and had a stray part blowing at the end of it, and maybe make the blade a tad more crescent(not anything crazy like a near perfect circle, I hope you get what I mean), and possibly less.. pick axe looking, right now it gives me more of a cone-like thorn effect..

Though my critic is more on the stylistic level and maybe a bit cliche, I hope it at least gives you some outside perspective.
