... here is a small but quick look into my work ...
At 1 minute... the video is about 120 times as fast as the actually time required. Such a drawing usually takes 2-3 hours. It always depends on how complex the subject is.
I like to simplify the shadows and reflections on the car, so it looks smoother and the shape is shown better.
Usually I only use three different pencils. That is more than enough to get nice contrast and gloss effect.
No matter how long it takes ... it's always fun!
