Oh, well, you're welcome
I was writing to a client just a few minutes ago for who I'm working on a map of Lake Winnebago (Bees's relating her life...) and I finally put my finger on something that I have in mind since I saw your map this morning. Your map with those colors reminds me this wood map I found when I was looking for reference for Lake Winnebago : burned lines, strong shadows made by the 'real' 3D relief. Something authentic, almost like a 3D model. So, great job, once again ^^
