@LitBoi But I did look closely, that's how I noticed.
The cloth on his right arm has no breaking line, that's all the same arm. Pretend it's a maze you can follow it from the shoulder to the wrist without being blocked.
Note as well that his shoulders are squared or at least even, your left forearm couldn't sit that vertically on the right side of your body with your shoulders squared. Give it a try, it should be pretty clear then.
