Good access and exit to and from the stand site is critical...human scent hangs on vegetation for awhile. Deer may or may not spook when encountering your in/out trails, but they WILL eventually figure out your setup if you use that route often. Don't just work the wind relative to your ground stand...work it relative to how you come and go.
The BEST face camo is a headnet turned backwards so that little eye hole is in the back of your head. Yes, you can't see quite as well with the netting over your eyes, but at 15 yards it makes little difference. And your face will be all but invisible to the deer.
Beware of ticks if you sit low or in vegetation. Deet won't work for long, clothing treated with Permethin (don't put on the skin) works best.
Unless you tuck your pantslegs into your boots, wear drab socks. You may look 'camoed' when standing up, but sitting down your pants may hike up enough to show those white/light socks you have on.
Once set up, always draw your bow from several angles to make sure it clears brush, trees and ground.
Eat an apple or pear, etc. before hitting your stand. Nothing like warm bad breath to flag your whereabouts.
Knee pads or a foam pad for kneeling can be handy for shifting into shooting position from a sitting position once deer are spotted. Clear all leaves away in a 360 around your stool and sit to allow slow 'melting' to your knees from the stool (rubber boots best...more flexible). Minimal noise, minimal movement, maximum shooting flexibility.
