Such a cool piece, Constantine :D I love it!
The design is really neat, and I love how it had come to be! You were stumped but then the word itself lend your creativity towards the ideas of space and sci-fi themes :D Did you know that I had also created an original character named Cassiopeia? XD What are the chances, hey :)
Gorgeous composition and I am glad you decided to stay with the limited colour palette for this one :) It really makes the Apricot planet pops out of the canvas, and yet we are delivered a very retro-feeling of an artwork from the space-race era :D Gorgeous!
PS. it looks absolutely AWESOME on the tap, too !!!!
