This is another quick experimental sketch using the custom shapes tool in Photoshop. I'd call it a "speed painting" - but the techniques used are a lot more like collage than painting
Like a number of my illustrations found here on DA, this is inspired by the colorful and dramatic sci-fi paperback cover art I loved so much when I was growing up.
EDIT: After posting this image, I decided to rework it. The alternate version - "Passing the Structure" - can be found here: [link]
