Did you ever get that feeling? Your just walking around, in the tram or wherever and you see a face, a car, a house, a landscape, whatever and you feel you HAVE to draw it in your sketchbook.
Well, it happened to me yesterday night. Going back home in the night tram and I see a guy sleeping. He had a face, a really expressive face, I had to draw. At first I doubted, what will the rest think? (was with some friends) he just has to start drawing right now? But then... what the hell! So I took my skechtbook and a brushpen out and started to draw. It was like a 20 sec drawing, I didnt want the guy to wake up, the tram was moving, so it didnt turn out very well. I put the sketchbook back in my backpack. But the feeling was still there, and the drawing was no good, so I took it out again and drew until I had to get off.
Then I moved to one of the back seats of the tram in wich I transfered to, and started to draw again. Lots of people sleeping, so I could take my time.
Have to do this more often.
