Featuring the fictional super-massive black hole Gargantua from Interstellar, Nebula gasses, and a Mars-like planet with thicker atmosphere and plenty more water :>
About 7 weeks to complete from beginning to end with many gaps inbetween. Most intense work was about 8-10 hours per day for select days.
I'm happy with pretty much everything in the painting, which is rare for me!
I will definitely have this printed and displayed on my bedroom wall to really blow people away. :3
