You thought Martians were green humanoids? Ha! This is what they look like. I got the photo from a friend at an agency in the USA, after they discovered them in the Martian oceans. Can't really tell the size from this picture, but I think they are huge (or tiny?)
Object made in Structure Synth. Rendered in Bryce 7.1 Pro with an abstract HDR as only light. Exported the result to an HDR and tone-mapped in Picturenaut. Signature in PS Elements. The black grid at the bottom is an artefact caused by the export to HDR, which is not always perfect.
Hope you like it!
