I did a couple more but ran into one of the many problems that tests my decisiveness (a test I am unlikely to pass). A number of the tiles as I had planned them take place in older forest, the type with big old trees and less undergrowth. Unlike the smaller trees the foliage is high enough up that it would not impede travel only the trunk would. I experimented with several ways to show this:
1. Dimmed cut off. Leaves me feeling like I want to squint at a part that isn't supposed to draw my attention.
2. Cut off view where you can see the rings of the tree. Doesn't look like its showing a break in the mapping, just a cut down tree to me shadow or no.
3. Blacked out. Seems OK information wise but not especially attractive.
4. Faded view of the tree top to keep in the style with the rest of the trees. Looks messy to me and doesn't highlight any useful information.
