please critique on conformation

This QH gelding is nine years old. He is only lightly used by a friend for trail/pleasure and is pasture boarded. He's a kind, mellow fellow and she wants to sell him. I have some mild conformational concerns but will say nothing now so as to not influence anyone's view.
Positive and negative, if you please.

Some shots were taken in the winter when she has a hard time keeping weight on him and some were taken the following summer (this summer).

Anyone? Just curious here. I don't know that much about Qh's so need a practiced eye.

The pictures aren't good for critiques. He needs to be standing without his head turned and not eating. There's a sticky in this section that will give you some mor information.

Get pictures from the side front and back. That will give people the type of pictures they need to get a full picture about the horse.
