Alien Invasion

Well this is a drawing I've been meaning to finish for some time now. You see, I took a Science Fiction Literature and after a long, awesome class, I decided to draw a pregnant extraterrestrial lady. Officially she is from Mars, and she has the stereotypical "green people" look, as you can clearly see. The blue on her belly, sides, and under her eyes are bioluminescence, like the stuff from lightning bugs or flashlight fish. I had a lot of free range with her, but I still wanted to keep her humanoid, like how most aliens appear in old school sci-fi. Why is she here? Perhaps she's here to mate with our men. Maybe she's already mated with a member of her species and she's here to replace our race!! Actually, I think she's just here for carrot cake...or was it cheese cake?

*EDIT* I noticed I didn't color a small portion of her head dress, I went back and added some pinkish.
