I agree with everyone else, from what I can see (these pictures aren't very good for judging conformation, especially with that mud on his legs- it makes it hard to see them) he has very nice conformation.
Faults-wise, his front pasterns look to be upright to me and his back looks a tad long. What concerns me most are how his front legs seem to bow inwards in that first picture- they look nice and straight in some of the other photos, though. It might just be his feet, they look like they're in need of a good trim... But if his legs really are concave, I personally would not jump him.
His pasterns are nice and short, as are his canons. His shoulder has a lovely angle and seems like it's pretty open, and although I think it could be just a tad bit bigger, it's still very nice. His neck also looks nice, maybe tied in just a bit low, but overall I like it. His withers seem to lay back nicely and he has a nice round barrel with a decent depth to his girth. His hip is just lovely, I love it... Big and powerful, and beautiful croup- if you want to try him on barrels, I think he has plenty of motor back there.
Overall, he's a very handsome boy, I like him a lot! If you could get his feet trimmed up and take some pictures of him standing on a flat, level ground (such as a road, if a paved one is nearby) I'd love to see some more pictures, that would help us give you a much more accurate critique. As for what he'd be good for, I think that, like everyone else has said, he'd be just fine doing almost anything you wanted at lower levels.
ALSO, that second picture is hilarious, I love it!
