Update, I've finished the first three tiles, with 8 more on topography to go. Then the actual work begins placing settlements and drawing political boundaries and roads. I'd done this historically per tile but I'm trying it holistically this time. Let's see if that's a fool's errand.

You can compare the topographical sketch I made to the updated version and see the improvements already. I've reduced the saturation on the sketch topography for the updated version so you can see the changes more clearly.

The stroke formatting isn't 100% consistent but that doesn't matter as they're all separate right now. When I join the SVGs together and merge the paths, they'll unify by design.
