Looking for Opinions on Bloodlines and Conformation

Hi there! Long time lurker here.

I’m looking at buying an Arabian colt in the hopes of training him in dressage and endurance riding, and I wanted opinions on his bloodlines and conformation for what I have in mind. I want outside opinions because if I get this horse I intend to keep him till the day he dies, so this is a big decision to make.

Dam: Magnum Psyrena RRX
Sire: Thee Hombre

Here’s a picture of him. The colt appears to be built a bit on the downhill side. Owner says he should mature to around 15hh.

Opinions? Thoughts?
