It's some kind of space galleon. I choosed a black/white/trans neon color scheme that i think works well (and reminds a little about blacktron). The black struts are supposed to give an "industrial" vibe to it, and of course provide the curved ship-like shape. The yellow fins are meant to recall sails (they're indeed "cascade resonance solar collectors" or something like that :P), but with a more punkish style.The cannons and the mast complete the theme mixture. There's also a brick built skull on the mast, symbol of the bad intentions of the crew.
The roof is weakly attached, can be removed to access the inside where two minifig can seat.
It turned out much smaller than i was aiming to (it's only 204 parts!), but otherwise i'm very happy with the results!
