Fanarts is pretty much everything the fans made based on movies, tv-series, books or games, without having the copyrights of them.
In this case, its Star Trek, copyrighted by CBS Studios and Paramount Pictures. Both are VERY strict against every commercial use which they do not approve.
So, yes this image is made by me, but it use the intellectual property of the Star Trek rightsholder with the designs of the ships and stations.
