He looks pretty 27ish, small ears, not a real big body. He doesn't appear to out weigh the forkhorn by much. In the photo where he is turned facing, it is difficult to tell if the antler shown is only white in color, or if there is extra width that is brown in color ( on animals left antler , or right side as we view it). It may just be background or vegetation. If it is brown horn on that side then he may in fact be 29ish. Looks like brown vegetation to me though. I don't see any reason to want to score him unless you shoot him with a bow.
A couple things to note, Video camera lenses distort images and make them look wider, and decent bucks with short g-2s tend to look wider than they really are.
