Is this Duke from your barn? He is just two years old?
From these pics it looks like he is all legs, LOL! Might need to fill out a bit? (Is he still a stallion?)
He will make for a fun cart horse if you decide to train him once he is matured.
How tall does he measure right now?
His toes could use a trim, might help judge how he actually stands...but his legs do look nice and straight.
With his pretty symmetrical markings side to side he could score pretty well in Color Classes too.
I think overall he is a pretty nice looking little guy, but then I am no "expert", just giving you my personal opinion....
