Looks like your after a heck of a nice one there. great shots and as well excellent tips of the photography. Lot of people dont realize how much they loose in resolution when ooming. More often than not its better to take a high res pic and then use the editor to zoom in .
Good luck on your hunt. Im going to get after some mulies on of these days myself.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
