I did this one in two sessions last weekend. It was really time consuming. Toughest part is the car. My biggest problem with vehicles are the wheels, to get them look right isn't easy. Else it is a scene with a lot of buildings and a lot of coloring work.
I like old American (Gangster) Movies, so I took this one in bigger format. I think it is a nice idea to paint the car and the person only in gray tones. Makes it look like they are taken from an old black and white movie.
Paper: Winsor & Newton, cold pressed , cellulose. Format: A4.
Idea is from a YouTube video. Technique is line and wash.
