Your lower leg is quite nice. You don't have to lift your chin or look UP, just pick a spot ahead of you and focus there. (Or around to the side if your next fence is around a bend; many professionals are looking to their next fence a stride or even two BEFORE they get to the one they're jumping! It helps balance the horse for the correct landing stride for the direction you're about to go)
Please wear a helmet while jumping. You're higher off the ground and running a greater risk of falling than you do when you're doing flatwork, so the risk of serious brain injury are MUCH higher. I live with a MINOR brain injury and it's more debilitating than you'd think, mostly because of the chronic migraines it has left me with. I was wearing a helmet at the time of the fall; if not for my helmet, I would be dead, or worse, a vegetable.
Your position is strong enough for an automatic release, and your horse will probably thank you for it. I feel that short crest release might be more restrictive than you think. Personally, I use a short automatic release (like Foxhunter described, elastic arms, straight line from elbow through wrist to bit, but I don't let my horse bring my hands forward very far) because that's what works for MY specific horse to maintain control over fences. If I have to throw the reins at her I can, and do, but she responds best in MOST situations to that little reminder that yes, I am there, and yes, I am in charge. Your horse looks fine with a longer release, and has lovely form over a fence. Take advantage of that! Develop a really nice automatic release!
