I'm definitely not a conformation expert, but I did notice a few things. His croup is quite angular, and he lacks muscle in his hind end. I like how wide his chest is, but his shoulder looks a tad upright. In the second picture he looks light of none, but that might be the angle. His legs a rather straight, although it looks like he toes out in the *slightest* way. Neck looks a but too skinny.
Some more pics might help! :) anyway, what a gorgeous colour!
