The problem with this is we don't know what he looked like before these pics. The best thing for you to do is put Bean in your lap facing forward, then put your fingers on both sides of his head (close your eyes if you can) and feel down his head, muzzle etc to see if you can feel an irregularity on one side.
Do his eyes look okay? Does he have any lumps in his throat? Hold his sides to your ear and listen to his breathing as well.
