OP, please get better pics. I'd never critique a horse based on such a pic. I doubt if I'd waste my time to go and look even. If it's taken from the ad, then they did a bad job advertising it.
agreed - and as an aside one of the hall of fame eventers was a 15.2h horse. Don't forget teddy o'connor too! Many of the games GP horses aren't above 16.2h (Gem Twist for example) as they have less hang time OF and are more agile and can make quicker, tighter turns and so on!
