I've been writing a series (crappy but still) based on Mars colonization and since then I've been turned on to all things Martian, so to me this is quite a bad-ass peice of art!!
Hmm i'm not sure if i've said this already or not, but i think Phobos isn't round. Its void of atmosphere and gravity and thus has a very asteroid look. I'm not quite sure if its Phobos, but i know its one of the moons.
but the pictures are a little bit to big...
You did a great job. Very impressive.
kinda reminds me of Doom!
