You nailed it! The map no longer looks like a Salvador Dali with floating rocks - very nice. Your coastline is a little rounded however - the lines of dark and pale overlay just back from the coastline give the illusion of even more curvy roundness to the coastline and perhaps you might shake this up a bit. But the sea part of this map is absolutely perfect and lovely. I'm not 100% convinced of that Portuguese Pavement as a texture.
