I've looked through several forum posts and I believe I have my forearms and biceps matched up properly.  I'd like some validation from a trained eye if I have them matched up.  I do know that the 11 bump forearm piece is the left forearm, and the 12 bump forearm piece is the right.  I also know the bicep with the 'thumbprint' is the left bicep, and the other one is the right.  I also know that two sides that match up on each bicep have an inward curve, which I have matched up on both of them.
