I like this one a LOT!!
It looks like you raised the sea level a "bit"....by how much I wonder.
I tried doing this with a collection of topo maps I had back in the 80s but smaller scale (eastern Canada and US) and colored blue all land below +100 foot elevation....man that killed the eyes
i changed elevation by different amounts in different places -- sometimes i raised it, sometimes lowered it
this is really nice - Russia and the vast sweep of the sahara were lucky to survive.....
