sorry, maybe this will elucidate what i meant by "the jaw is straighter" - you see on the reference how the corners of the jaw are in line with each other? on yours, you've placed the left corner of the jaw lower than the right corner. it's not a big thing but makes your face look a little tilted, since the jaw will always have a straight line from the left corner to the right.

sorry i didn't explain that well :) if you fix the issue you could also show some of the underside of the jaw like the reference does, hope this helps!! bear in mind im still a super beg myself so please take this with a grain of salt.

pink is where the jaws ought to line up, red is where you've placed yours. i think you've gotten his expression really captured though :D
