This is just a LOGH inspired ship. It didn't appear anywhere in the series. I just made my own design but used some elements found on Imperial ships found in the series. I do plan on modeling some ship from the series someday.
Thank you very much. It's not really anything different from what I do with cars except the texturing, but I am surprised of how well it turned out and that everyone likes it. I almost feel like someone else made it.
