Ones of 31 Buddhism realms, Brahma Paritasubha Bhumi, Brahma Apamanasubha Bhumi and Brahma Sibhakinha Bhumi for our own project, Bodhicitta Board Game. No explanations I can offer here because I don't really understand anything about this realm. Maybe this will help: https://en.wikipedia.org/wiki/Buddhist_cosmology_of_the_Theravada_school#Arupa-Loka_.28Formless_Realms.29 ^^ The point is brahmas in different realms also has different aura on their own. Btw, I use Sharpie Fine Point and Sharpie Ultra Fine Point to do lineart on top of my pencil sketch and then tweak them over on variations for each other realm.
