Wow a sporting goods store finally set someone up properly! Its a miracle!!!

The bent elbow is actually what you want. Yours is bent more than usual, but its just fine.

I like to cut my arrows to be even with the front of the riser, but you could cut yours down to about1" infront of the rest. Or 1" in front of the riser....its really your preference. Just make sure you have a shop do it with a highspeed cutter. Carbon arrows cant be cut ANY other way.

The only form thing I can recommend to you is to relax the bow hand...it isnt gripping the bow, but it looks like your fingers are tense...(maybe they arent, but they look like it to me). You want every muscle in your body relaxed, especially your; face, hands andarms. Back muscles are the only ones that should have tension.

Looks like you are on the path to success already. Good luck and have fun with it----Matt
