Marmot Problems

Ok so the Marmot does not have enough verts on it, when I smooth it, it becomes better but they aren't in a round pattern around the mouth.


I tried using curves to influence the face and as you can see there is not enough to make nice shapes...
So I went into Mudbox, which will be able to make the shapes really easily, but it says that there are some faces sharing more than one edge. I think this is where there are a couple of thick lines of verts in the head... I can do the facial shapes pretty easily if this can be sorted by the end of the week please
