You have a really fine map going here!! I like the colors, the coastlines are excellent, the rivers and lakes look good, nice labeling, everything.

I have two suggestions.

1. Don't use the same texture across the ocean and land. I really like the texture for the ocean, but you can see where the same texture crosses the coastline boundary and that looks wrong. Choose something similar but noticeably different for the land texture.

2. Add a narrow region of lighter blue to your ocean along the shorelines to suggest shallower water. If that lighter blue also runs up the rivers, that's ok, or you can avoid that as you prefer.

Overall, an outstanding job!


PS. I think you would get more attention and comments if you would upload your images to CG rather than dropbox. I know I don't usually follow links to other sites like that, and it's nice if the image shows directly in the thread where people are likely to comment on it.
