Painting through the Universe: Mars

Despite how it may appear, I have not given up on Painting through the Universe! In fact, I have a new addition today. I have to admit, I felt quite a bit of pressure painting the Red Planet, but I think working my way through the panic phase of "Oh my gosh I've screwed it all up!" was worth it. This one, like most of the rest, has a black background, but I'm not sure if I'll continue that trend for the rest of them. Thoughts?
