LBR is right on. And I would add that you should put your exact hunting cloths on when practicing. Things to look out for when using thick clothing is underdrawing and bow arm elbow rotation (I've been known to have problems with both [:@]). Also keep your shoulders at 90 degress to target, don't drop the bow arm. And don't forget about the in tight shots, practice them hard. Personally, 25 ft is way to high for me. I like the deer in close and at a decent shot angle. 15 feet is my max.
