It looks fabulous. What tools and techniques did you use.

Have you seen Zaon Maps ? (https://www.zaon.com/) They used to have some sample maps on their site but they seem to be more hidden now. Anyway they are just awesome too. I don't know how much more they have in their books but the sample was amazing. They still have some planets there tho...
