The right cheek got pushed out as if it was a mask because of that shadow.
Also the whole face looks more like a mask - the mapping of the face is odd, in my opinion. Try stretching the face down a bit.

I feel ya, spent my whole 5 hour driving course staring at the instructors face
for shading tips.





UPDATE: jacked a burlap texture, shaded more, changed right hoop to plug, detailed neck(needs more mapping adjustments)
probs gonna do another round of re-highlighting (and probs shadowing) to get that greasy indian feel. looks like i need more on forehead, still need to remake(or attempt to) the eyes. going to drop shadow turban better
rest should be a cakewalk. just need to add back of head
NOTE: I need help with neck mapping suggestions, please post them!
