He seems to be of the "newer" model of TWHs. I had the older style which was massive in size (only about 16 hands) but wider then a mac truck and muscular as all get out. My new mare is of the finer bone structure. Her front legs are straighter but her overal body structure is close to this gentleman. My vet really liked her confirmation so my assumption would be, other then the slight calf-knee, he's a nice looking horse.
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
