The only marvel of that ship is how it flies. There is no "air" to it, by the looks of it. No thrusters, propellers or balloons. Nothing.
The design is VERY 2D. It's all like one big giant line from the side. No change in shape to round it off or anything. The walls are spammy, people are indeed right; you could've easily used larger bricks and some trimming to get rid of all those annoying lines. The fact that we can see the exterior of the ship from the inside is bad on it's own, unless you were going for a grungy interior as well. Hypothetically if that were the case, your walls would be metallic, floors, etc.
There are no windows or little details. No side controls, gauges, panels... It seems like the only controls this thing has even in an RP would be the "laser button" and the control panel computer.
