I agree with what Leel said, it looks like it's bending towards us instead of away like it logically should (well, I suppose it doesn't need to bend away, it just looks weird, personal preference, if you will).
I'd drop the cracks, because they look more like just a cluttered mistake to me, and the legs look weird, just because they bulge out so much. Other than that I don't see anything, it's really well done, I'd say.
