That is pretty amazing. Have you heard of a SJ artist called, Silverblade: The Enchanter? Silverblade has made a lot of 3D Spelljammer art. He has made 3D models of many ships and has been kind enough to allow a couple of other artists to use his models, to make their own art. You would need to credit him, of course, but I think he would be happy to help you make more Spelljammer pictures, like the one above.
