well if you are comparing it to the ship on a certain website. That one is too high poly for the game. There are a few who will do up a ship for you for a modest fee. Try
www.staryards.com for one.
Have you tried it in game. The reason I ask is the screenie is from sfc1, not 3. I thought the guy who converted it, did an excellant job with the glows and Atheorhaven did a nice job with the break. Maybe someone can post a screen of it from sfc3. There is also a second version of the saucer textures in a seperate folder that can be swapped out. It will make it look more TNGish.
I don't think I will be updating it myself. I'd rather move on to new projects, except I don't have the time for them atm.
