You look extremely solid for 13, I wish I started that young let alone had a pretty solid form at that age. A few note though, you really carry your backswing to get it up that high, This down the road can and probably will become an issue, it is much better to just let it go naturally but its not something you just want to immediately scrap. Also you aren't under the ball much at all, I understand your younger and may not have the strength built up yet but its something i'd work on.
But besides that you look solid, just keep working hard, find a coach if you can to help guide you as you get older and bigger.
Oh please shrink your signature, you can just move it to your profile or just delete it...
