Whaaaaaat is going on up there.
Texture misalignment everywhere, the walls are made of lights (?), the X is made out of who-knows what (A custom texture, I assume), pirate skulls?, vertical rock walls among all this, barrels made of barrel lids, AND IT'S NOT LIT OR VIS'D.
Please do texture appropriately. And VIS/RAD. And not release your first few maps.
