I apologize for his square-ness in the pics. When I was trying to pick one to put confo dots on, they are all very different - he was a little anxious and being a young horse didn't want to stand still or square

In the conformation instructions it says that it is common for a young horse's legs to be a little camped under...
I'm going to try and look at his front legs again this weekend to verify the crookedness.
His head is definitely fluffy but I see where he does have kind of a block head

He is growing very slowly though so it might catch up with his at some point. Hoping he grows up to look like his brother!! At least he has an amazing personality to make up for it is he doesn't.
The things that you guys have stated/noticed - would any of these be enough for you to pass on him as a purchase? Is his back too short? What about cannon and pastern length? Too hard to tell as a growing young'un?
Thank you for your comments!! Very much appreciated.
