Alien Buggy was started as a design sketch, then later I added an environment. I used mostly graphite pencils, sticks with blenders, Verithin for sharp edges. Then I cropped and added the border in Photoshop. I truly enjoy doing fantasy designs with unusal characters.
I find working out design in pencil works for me because I can do them anywhere. I find it usuful to turn to Photoshop or Painter to actually not continue the sketch into a digital painting, but to use them to work out composition, color and values quickly then apply those ideas to traditional media.
Hope you like the Alien Buggy,
