hey Tappie, even without considering this wasn't a complete kit and involved some individual conversion, I think you did an excellent job. Regarding the eyes, not sure if its just an misplaced pixel, but his right iris does seem to be larger than the other. Generally I don't think the eyes here are too big or incorrectly shaped - just the white is too stark. So try a light wash of pink/brown and see if that helps eliminate that little problem.
