This is about 50 studs long and 28 wide.
Sorry, but I can't really show the interior. It's kinda hard to get to...
It was heavily influenced by the Kushan multi-gun corvette from Homeworld. It has 3 crew members.
overall this is quite good, the thing I like most about it is how you managed to make it so big without boxiness. I'm as of now working on a sixty four stud ship thing that I have posted a WIP page for if you havent seen it.
The details outside are good, but I'm a bigger fan of interior details, which is why many of my ships are a bit boxy, like you mentioned in your review. I still would have given it a four, but the engines colors don't seem to match the scheme of the ship.
