Yeah, I'm having trouble with saying "water is here" in the ocean areas of the map, without making it look, well, kinda bad. Working on it though. Maybe a nice cloudy layer mask will help clear things up.
Edit: Yeah, or not. When in doubt, make the waves a brush and distribute in a way that looks good. What do you think? I'll make more wavy patterns in GIMP for the brush next time, but how does that work...maybe stylistically is the word I want to use? You get my meaning.
