Quoting Ewen Albright
Nice main picture. How do you do that?
Thanks! I cut out the image of the MOC using an image editing program (Fireworks, though there are free ones that would do the job) then I placed it on a picture of Mars taken by NASA's rovers, then I cut out the sky and replaced it with a Hubble telescope image, then I traced the logo of Space Police from a picture of a box, and placed it on there along with the official Lego logo I found on the internet.
