A couple of months ago I contributed to Thunder Chunky's "Back to Draw the Future" project, where I had to make an image based on a random character from Back to the Future 2. I made loads of rough sketches in the process, but in the end I could only use one for the project. Looking back through my sketchbook now there was one sketch I really liked and thought I'd work up as well. The original project had a limited colour scheme, so I've used the same again, and also done a more realistic version. Which do you prefer?
