Looking very good. Metallic shipsets are a very dangerous thing as they can look terrible or they can look amazing (like the Federal Union) This one trooper falls into the amazing Category
I really like the overall look of that ship, it's not very alien though, more like something humanoids would build (obviously cos it was humans who made it in starship troppers) I like the look of the engines as well, they seem to grab my attention. Overall looking good!
