RE: hows my form (pic)
Another thing I notice is avery open stance.Pull you front foot to where it is a little more perpendicular to the target.Or more along the same plane as the bow.Open is fine but you belt buckle is almost facing the target.Get it more toward the camera imo.This will help with the draw as well.
The loop looks long as well and that can help with the overall if it was shortened.
The more I look at the picture,the more I think you can have very acceptable form with your current equipment as is.Shortening the draw might be an easy/quick fix but MIGHT not be the best overall fix.Another area of concern for me is your bow forearm.It needs to be turned more away from the string than it is currently.Rotate it slightly outward.
