SOme quick ones: -end with a quad @ the corner of the mouth and the inside of the ear -extrude an edge inward for the mouth at the very least - the eyes are to close to the center - nose is to pointy My advice is download as much refernce photos of a tiger you can find even better is to have some bookmarks to some video's since a photo is only one moment and you could be working of some odd expression I prefer footage with headturns those are the best
