I see what your talking about, his left elbow is out of frame. The right elbow is has disappeared because the arm is pointing forwards, making the arm disappear, and im not great with perspective, im still learning. I have mentioned that my anatomy is off so it appears unatural. l never said this was a master piece and im the best drawer and you dont have to congratulate me, everyone is entitled to their own opinions. But next time, pls be more polite with your criticism. Ty :)
