I don't think you look too big on him at all @SeeingSpots
I must get a picture of me on Oscar sometime. He is so much fun to ride. My biggest issue with him is that his saddle is too small for my bum!
@SeeingSpots I was just thinking you look more comfortable and relaxed in the last picture where your stirrups are a little longer. Its okay they hang below his belly. I really don't think you look too tall on him.
Ponies do rock. Next time I have the choice between a horse or pony it will be another pony. You can't beat their characters and mental and physical toughness.
