Height in the tree will help you after the leafs fall. Don't be afraid to hunt small confined areas. If it's thick the deer come through way more relaxed. you only need a small shooting lane to kill a deer. Have you been up the tree yet. Spots look different once your elevated. Use your scents to get the deer to stop in the right place to offer a shot. Also a good way to get scent to a location without walking up to it is to put some on a stick and toss it over to the spot.

Good luck.
