I have recently completed a s/f book which has been fully edited and ready to go and I am now trying to find a publisher for it. If I can't find a publisher I may try to self publish it as an ebook. What ever the result turns out to be I am looking for some art to go on the cover. I am looking to have it depict a world with lots of small continents, polar icecaps and a small orbiting spaceship. The world has no visible signs of intelligent life from orbit and the spaceship is a singlemanned craft with a large hold containing an even smaller craft used to land on the planet. Would any artist out there be interested in creating such an image?
