Hey, keep your confidense up you probably saw more deer than alot of hunters. Sounds to me like your doing all the right things. Just consentrate on the shot at the heat of the moment. Pick a small spot on the deer to aim at and talk yourself through the the release.I tell myself anchor,aim,elbow out, aim, release every time I shoot.
As far as scouting goes the most important thing to look for is DEER. I would say some people get so involved looking for sign of deer they miss the deer.
Can you tell where they are bedding? Can you tell where they are feeding?...Put you camera on the most active trial you can find probably near some natural food. good luck next year...practice shooting,
