I can't do pictures but ours is 14.3hh I'm 5ft 8 and daughter Is 5ft 6 so I'd say if your looking for something around 14.2ish then no your not too tall
I have a purebred connie 2 year old filly who is 14.3 now so will make 15.2 minimum. Im 5"7 and will do the backing etc myself. I assume she will be sold to an adult home and wouldnt think someone your height would be too tall at all!
