The ocean looks great, and I like the sea in post 13 a lot, too. The coast, for some reason, it seems to me like the upper-left corner is higher up elevation-wise than the lower-right. I don't see the same effect in the sea/ocean tiles (or the coast in post 11). Maybe it's an optical illusion, or the relative positions of the ship and sea monster. Or maybe it's because it's way too late at night. I'm not sure. Thought I'd mention it though, in case others are also seeing it and debating if it's just them or not.
