Hi BlindBlake,

That is a nice map. Before I comment on it tho I should just set for the record that a large scale map is one that is close up such as a town plan or a dungeon and a small scale map is one that covers a region or country. Now of course your world could be very large indeed and this is but a tiny bit of it and thus large scale in comparison to the world as a whole but generally stuff with mountains and land areas in it are small scale mapping.

The mountains look like a good shape. I would suggest that you flatten the lake at the height of the water. Whilst its very useful to have the sub surface bathymetry for other reasons, for a render of the map as a realistic place, you would not see much past a meter or two under the surface and therefore not see the bottom of what appears to be a very deep lake.

But to be clear, I like it a lot.
