This is really coming along. And I hear you about the islands - I spent quite a while manually clearing islands, stray lines, and oddly placed lakes from my world map (way huge file too ... o.o ) That base texture your using is great, and the colors are fantastic. Personally, the outer glow is a bit too cyan (as opposed to the blue of the actual ocean color) but you mentioned you'll be working on that later ^.^
