Well i am happy to here that the deer is doing fine.
But the shot was still a bad choice to make, First off the shot angle was a low % shot not that it wouldn`t kill him? But the chance`sof you making a perfect hit dead on are low.
(imo) you should have waited a little longer for the deer to turn broadside or just quatering away Like others havesead.
2nd If your not sure of the shot you have made and the deer is still standing send another arrow on its way Never hurts to be sure!
We all have to learn and the guys here are just trying help you for the next time this happens and if you keep hunting? it will.
Good luck next time.
