Alrighty, for the far left one, the head is tilted way more to the right and upwards. Pay attention to how his eye on our left its tiny compared to the cheek bone, there should be way more space for that to exist and you indicated the eye on our right as it appears in the reference, but since the rest of the head in yours isnt tilting that way it looks out of place

For the second to the left youre getting a few things right, but notice how his head tilts more towards the right and the essence of that angle is in that tilt. His jaw underneath should go further back, which would push the rest of the cranial mass. You'll notice the way you drew his ear, and how much space there is of his head going behind the ear, but in the photo it nearly tangents the ear to show the full mass of the head. And his nose is slanted in yours, like its pulling to the left, but with that proper tilt of the head it'd be a better indication in perspective.

for JP most the problem is the spacing and size of the features. Like the eyes are slightly farther apart, and his lips are a bit wider, and his nose has more structure near the end. His jaw is also fuller, its goes down lower and the top of his head is higher in the reference to show that very egglike form of his forehead.

For (fry?) his eyebrows are higher up, almost ladylike. and the forms of his head like his nose are larger. I hate to say it but his face is less symmetrical than what youve indicated. His eyes are lopsided, his nose is crooked, his lip is off center. The guy you've indicated looks quite menacing and evil, closer to like anthony hopkins maybe, but in the photo he seems gregarious and charming in his fatness lol.

Hope that gives you some ideas ;) dont be shy from posting more!
