When I created my map_h using SRTM data I set sea level to -10m so as to pick up the topography below sea level.
Later when you make map_c this will define where the coastlines are.
In map_T use map_c as a template to set all the sea area to water texture, otherwise land textures are visible in the water.
When you make map_c use an airbrush tool or similar to soften the edges of the coastline, but use a hard edge tool for narrow rivers otherwise the land merges in too much.
It takes a bit of experimentation. I am still adjusting things.
