Personally, Judging from his other mounts, I think he has a guy set aside that does a quality job to the deer he really wants to appear good. It's probably something where his friend just started taxidermy, and wanted provide his friend another opportunity to put his skills to the test or to just improve on. I think it offers sentimental value to him, in this regard, and therefore, I think he'll be okay with it. I'm sure he'll have times where he'll wish he took it to main guy, but I think it meant a lot to his friend by letting him mount his deer for him.
It's not that horrible of deer mount considering what he payed for it. There have been a lot worse mounts done and there will continue to be worse mounts being produced.
