This is a sketch I've done yesterday evening over a nice dinner, and I wanted to try a different way to color it. So I played with some worn out textures and transparencies, I used this technic on an illustration I've done for King Kong a while ago, but never on my sketches. I find it very pleasant and interesting to do.
I have more from last night that I'll color and post soon.
Also, I love to draw in cars, I find the "wobbly" line you get out of it very interesting. This morning, I decided to draw the guy in front of me while I was walking...quite a challenge (it started to rain too). I'll do it again. Here's the result.
