Welcome. I suspect you must change your username now, eh?
While I know little about GHs, your boy appears very different, from those I am used to seeing. Maybe it is because we see so many who are overbuilt and muscled with sagging bums.
What a handsome youngster and in lovely condition. I would probably like to see a little meat in his neck (which will possibly come with age) and wonder if his pasterns might be a shade too long. I like his head and the fact his ears are always forward and alert.
I would like to see this boy in a couple of years. Definitely craves an English saddle and tack.
He looks a bit Appendix QH.. very much a nice TB shoulder (for hunters this is great). The only things I can see is he appears a bit back at the knee (not good for jumping) and he seems a bit straight through his hocks. Nice bay greying out.
