and yes, the face is waaaaay too wide. the bottom jaw is too thin for the current head size and is definitely an unnatural size.
and, the nostrils are SUPPOSED to be the same, it's like that in nature, and it's like that in pokemon. if anything, it just looks awful when it's uneven like you made it...
the shading also looks sloppily done, definitely doesn't go with the model at all, try to make it lighter and more cohesive.
it's like, the body is really good, but the head needs a desperate makeover... so please don't start on a shiny texture yet...
