This looks incredible! It really adds to the vibe and atmosphere of the game, much like your stellar - pardon the pun! - work with the Starshipper playmat.
It's great as a creator to see players having fun with your game, so thank you for sharing!
As it happens I am working on a playmat myself, and also starting work on an expanded 'spiritual successor' to RnR, utilising d20's to expand the gameplay. I hope to have something up in the coming months.
Thanks again for sharing and commenting!
