shoot sitting down?

since im a right handed shooter. id sit and draw my bow if the animal im shooting is on my left side. if its on my right side id stand up and draw my bow and shoot the animal down

 

It all depends on the situation I've killed deer standing and sitting from the stand.

 

I try to stand as soon as I think I can without spooking any deer. I have shot a few sitting down, but only as a last resort If I am pretty sure I can't stand without getting busted.
