Let me start off by saying the body looks absolutely great, especially the paws!
However, I agree with most of the others who have posted here, in that overall I'm not a fan, just because of the face. I think the justin would have been fine to basically trace and just redo the shading to look nicer like this. The facial features are unnecessarily and awkwardly large. The mouth is slightly too far open, changing the expression from the previous cute expression with a hint of doofy to just...I'm sorry to say, but a sort of blank stupidity. I'm sure the eyes contribute to that as well, I think having left them a more rounded shape on top would have helped to avoid this. As they are now, they look kind of tired and sad, especially if you cover the smile.
I think that covers my criticisms though, and I'm sorry if any of them seemed too harsh. Especially since it's not exactly bad, just not perfect, or what I'm used to and was previously quite pleased with.
