Critique Snickers, please?

Good evening, everyone!

This January I posted a critique request for my 6yo Latvian Warmblood gelding, using not the best picture, but it was all I could get at that time. This is how he looked:



Some time has passed now and I would love to hear your thoughts about his conformation, his strenghts and weaknesses , also - how does his muscling look to you? I've been working on it and hope it's going for the better.

Side view -



Front legs (sorry for the mud on them, we had a major downpour just as we were walking to the arena to get photographed) :



Hind legs:



Thank you for looking into this post. ;)

He has long back and is built downhill. Toes out in the one side & on the same toe in the front so I think he is crooked back to front. Good bone density overall. Decent neck but a thick throatlatch, common head but it works for him. Overall, he looks like a nice horse, well taken care of.

Good shoulder and neck set.
I don't see anything off about his front legs in those photos.
Bum high but his back isnt too terribly long.
I like his hindquarters
Back legs appear as though they would be correct, however he is cowhocked

Thanks for your input, waresbear & lilruffian, I appreciate it! This might be a silly question, but I don't know, really - is being cowhocked something that can be corrected with exercises, chiropathy, stretching or something of that kind, or is it just bone structure that cannot be changed?

And maybe someone has anything else to add? :)
