Hmm… I do notice some sharp edges on those stones that feel out of keeping with the otherwise rather-soft feel of the rest of the piece.

That said, I do quite like the character: it has a nice, soft, “fun” feel to it.

However, what do you have in mind for the model? Is it intended to be animated? Is it intended for in-game use? And if so, in what role? From how far away is it intended to be seen? These things (and others, I imagine) may impact whether it's well-designed for the purpose, I daresay.
