This is from a project I did when I went on a school for Illustration. The school was Fagskolen Kristiania in Oslo. The task was to pick a wall and paint a picture on the wall. We had to first plan how the picture are supposed to look like, and when paint it on the wall. The digital line art is the sketch of the wall painting, and the picture of the room is a picture of the actual wall painting. The last picture is from then i later  colored the digital version for fun.
