Hi,
Like I mentioned in my previous post, https://www.cartographersguild.com/s...ad.php?t=43394, I am working on a map for my book "Teacup".

In my main map, which is a regional map, I want to insert a smaller map of a dwarf mine that which leads to the fountain of youth. (Which is what the book is about.)

At the moment I am getting my inspiration from isometric grid maps, such as the ones posted here and here.

So far I only have a very raw sketch, which even I can see is not very good, but I thought I'd post it here anyway so that you can see its true progress.
