IMO, he needs more muscling in his rump and along his topline. I'm also not a fan of how his neck ties into his shoulders and then his shoulders to his back. He has a good bottomline though and I really like how thick his cannon bones are (I hate a skinny cannon bone lol). He has a very cute face to him and delicate ears.
