Hello, thank you for taking the time to work on this little project! I hope you have fun!
I forgot to add, it is not mandatory that you draw the dice by hand or 3d if that would take too much. You may simply paste or trace from a photograph of any black six sided dice in the appropriate position / rotation and I could add the constellations over that.
If you want to draw the constellations yourself, check the gallery of the campaign website and see all the six sides in the correct position.

Have a great day,
Gio
