What Whip Said. You did the right thing.
That said, I see you twice referenced coming to a full draw, standing, and shooting.
I don't know how others do it. As for myself, if I'm in a treestand, I try to get a shot sitting. But, depending on direction, it maybe better to stand when I first see the deer.
I can't picture drawing, then standing up while at full draw, then shooting. Others could weigh in on this.
I'm product of the '60's. So, you may want to discount how I hunt. But, I learned to snap shoot. It took a long time to "un-snap shoot." Still, I never draw until I have the shot. And, I only anchor long enough to be aligned on target. My arrow is on its way in a very short amount of time from that when I am not drawn at all. Simply, I couldn't imagine sitting at full draw for any amount of time. In fact, if I think that will happen, that I will have to wait for a shot I thought was there after I had drawn, I lower down and wait for my shot, then draw again.
Whatever method you use, and I'm sure there are other ways of looking at this, you should practice all of it in simulations before the season. So, if you feel you can come to full draw, then stand up, then aim, then shoot, you will have done this countless times before the season to get this method to work for you.
Good luck in you hunting. And, remember that hawks, depending on hunting to eat, make about 20 attempts for one success. But, they probably can't count. So, they don't get discouraged like us "smart" humans.
