The first thing I noticed was that the buck is "smiling". Deer don't smile. Also, that swelled neck is huge. I'll take your word for it that you shot him like that though.

If you get a chance, lookup some photos of real deer and compare them to yours. Close-up photos. That's the true test ... how much it looks like a real deer.

By the way, I don't want to take anything away from the nice trophy you harvested. He's a dandy and I would be proud also!
