Marsha the Martian Potential Cover

Here is a cover I drew up when I felt I was coming closer to the look I wanted for many of these characters. I like how it turned out but feel I was too timid with the covers. I may need to study drawing and expressing the cosmos in art form for the covers if I was every to really illustrate all of this. (Additionally, I have not ironed out the design of their ship, so this is sort of just a generic one).
