You ever thought of moving the head back? It'd probably even out his shoulders, plus you need to make sure the neck goes beneath the hair, too. He needs knees and elbows, too, not to mention some detail on his sleeves. His boots look fine- but he has no face.
I'll try something. This will be my first ever time doing something with sprites, too.
I know I didn't give him a face, but I didn't want to mess it up. And the "knee" I added to the last Link on the right's knee doesn't really look right, but I thought it needed something, otherwise the leg just looked like a stick. Actually- keep the leg straight, but cover it with the tunic a little! Say, the top two rows? The one grey square being the first one.
