Good work !
If you're on the stand get rid of the strap and anything elsethat might get in the way or make movement or noise.
If a deer comes up on your right side you have the choice of turning with much movement and noise or shooting left handed .To me the best choice is to shoot left handed. If the deer is far off you should be able to turn without too much trouble. Practice a bit and you'll get used to it.
And Watson , bring your revolver !
