Really like the map and thanks for the link to the heightmap. I also stitched together my map with places that I have a connection too. As for the rivers, I ended up drawing them with a brush/pencil at first then went back to my sea and land layer and added them in. Once that was done I updated the layers and was able to get a more consistent water color to work with. Look forward to seeing your final version (and if like me a final version of the first draft of many drafts LOL) Good luck.
