Like the Eyeball Collector drawing, this just started as a doodle in my sketchbook. I got carried away with it, and tightened the details up like a finished piece. I created the background color and textures in photoshop with the idea of adding a creepy, alien atmosphere... an interesting setting I had in mind, but not overpowering the pencil drawing.
Here's a color version and some WIP photos I took of the sketch in various stages.
