This build is over all pretty good. Some of the things that could use some fixing is the engines, they are a little big. Solution, I've looked at some pictures and all you have to do is make them both a little smaller, than you add one or two more engines in there. However it would still look fine if you didn't touch that. The other thing that I have a problem with is color, pretty much, It's a little too grey. All you have to do is add a bit more color into it and then you have one noice ship. Good Luck!
