I did this one yesterday and posted it at Sijun too. Based on a loose sketch i did. The two guys were drawn separate when i drew them more accurate
and the background were composited in later. I decided to go for a pretty Simple look. with one layer for a gradient, 1 with colors and another with shadows. Took about 2 hours all in all. I'm pretty happy with the expressions in their faces.
What do you think?
