So mayhap the wisdom of the crowd can tell my face shape? I used older pics where I have no or little beard, but that doesn't seem to have been a magic solution.
Because of all of them have different angles and poses, the app says to use a forward looking picture. Your 2nd pic is the closest to that and I'd say it looks like a triangle shape to me, maybe slight oblong shape as well.
I think his face shape is oblong. In first and third picture forehead area is covered with hair. So, considering all these things and based on his second picture it must be oblong.
