The head is worth 20 points, and all we can see is your hand mashing it. If he's pushing forward against your hand, he will make his shoulders look low and hollow out his back.
His rear feet are pushed too far forward. He peaks early and slopes off the hindquarters.
However, posing him better will make him look a little better. Remove your hand from his head and take photos from the front, back, and top view as well as a better side view.
