@d9nis nope, just good old pencil and some copy/paste :)
Hi nice scene!
Dis you use some stamps or specific brushes?
I'd love to drift off into the space you've created with a small spaceship. The black outlines around the planets are a bit harsh. Unless the planets are something that can be interacted with, maybe go for a purple outline around them as you did with the small red planet. Keep up the good work
Stunning work! Absolutely beautiful!
