This is my final image of my stealth ship and is also my first finished project.
Nice modeling , but I think your texture just went to a stealth mode 
Very nice model but your ship needs better textures and I still think it is lid to uniformly and doesn’t integrate so well into the background.
If you work on the texturing part and on the lightning (try a negative light from the right) then this could become a great render.
I like the ship.
But i have no idea od size, some detail like a bridge and doors etc. would give us more information about size.
