In this photo my posture is good, my eyes are down a little but my head is not tipped forward. My leg is wrapped around the horse, heel down, not braced. I have a straight line from elbow to bit and my elbows are by my side (could be a little better, but not bad) and my arm looks relaxed. The horse is on the bit and actively engaging his hindquarters, ears pricked and paying attention.
I am happy with this one, hoping for the day that I am fit enough to ride like this again. That is what I am working on now. Dinking around with Nina and not really working hard on me has left me slouched and soft. I am fixing that over the winter.
