Thanks all, yep, just some spaceships have shape like this. I hold this MOC using transparent system parts

Very creative design!

I have to agree with JS Can, it does look like an underwater vehicle. But I do like this spaceship, the surface is pretty busy, but the shape is pretty unique, but nice though. Anyway, good job, 5/5!

Hmm. Yeah. Does remind me slightly of the old Aqua Raiders sets... How's this MOC when you hold it? Looks a bit fiddly.

Great parts usage and color blocking on this. The surface texture is pretty busy, but you've got just enough flat surface areas with some of the the pieces to make this work. Love the various angles in the design, too. Nice one!

Unique build. It looks more like an underwater vehicle IMO.
