shouldn't you start again? this was from Jay's OBJ after all...

...anyway, i like it so far, The nose seems maybe a bit flat and wide. do you have an unsmoothed wire frame, a smoothed wireframe doesn't really show anything.

I re-did the UVs on my version and get a weirdness around the ears, I think they need to be a higher poly count or laid out in another way as they are more of a feature so will need more texture area.
