That's a unique camera setup.
Got any pictures of the other one, he's posturing up-to?
It's hard to guess at the age, maybe he's just well fed, or he ate something that gave him some gas-bloat.
It's a big deer, with full haunches and front shoulders and a "dunlop" brisket, I'd say 4.5 (+).
Old enough to be a mature deer, which makes him a shooter for me.
