Finished option 01 attached. I am working on another version which will be darker in the deeper section of the painting. It feels good somehow to have the dark arc shape against the bright background but I think it feels bit too bright there. What do you think guys? Please feel free to comment.
The process - only photo manipulation in Photoshop as per the clouds. I did model and render the planets and the star in 3d Max using VRay. This was one of the hardest paintings I worked on and I did not expect it at the start :)
Option 02 coming soon.
