The Paint has lovely, spectacular jumping form but is NOT an eq prospect.
Too round and thrusty a jumper. The best eq horses are fairly flat jumpers, allowing the rider to maintain their position and not make big moves. The Paint might make a great jumper or event prospect, or hunter prospect on a local circuit or unrated division with no color prejudice. Love how tight and careful that front end is, and how even and well-engaged he is behind.
The bay with the watch eye is a nice hunter type and seems to have the attitude, but needs to tighten up below the knee.
The grey is jumping way over his shoulder and showing less than stellar form. Appears relaxed and attentive, and I can't tell from the angle of the photo whether he took off very close tot he fence.
I am curious as to why these very green horses are jumping single fences? Or has the paint jumped before, just with someone else?
You appear to be a capable, sympathetic rider, however, you're showing a few bad habits that will limit your progress. You're pivoting on your knee and losing your lower leg in the air, which robs you of security and pushes you too far forward in the landing. The open fingers in the second photo are also a probem - more than a few riders have broken this habit by breaking fingers when the horse stumbles or pecks on landing; a few more have broken the habit after dropping a rein.
