That is a beautiful buck. I waited until I figured I had a deer that I would never surpass, but also it was a truly memorable day afield with friends. Money and space has a lot of sway here, just be sure you are using a good /not cheap, taxidermist. It can only be decided by you if you should do a shoulder mount. As a compromise, you could have a nice rack mount done, maybe with a well edited framed photo of you and your buck hanging with it.
