That first one is a hunters dream! Beautiful animals right there! IMO, get a bit further to your right so as to take out the other three elk and make your subject the first buck. If that's not possible, you gotta do what you gotta do, and I think you did well.
The second...there just seems to be something missing. I dunno, maybe SOMETHING in the background to give some depth to the photo, it looks like a giraffe walking in front of a green screen. Beautiful animal, but very plain.
Not bad overall IMO
