To start with I pencil in the outline. This took about 5 hours to do. Once that was done I went over it with white chalk.
After the white chalk has been applied I smudge it in and then start to apply the different colors. For this I used brown, green, and a bit of yellow.
Once the other colors have been applied I then smudge them together and afterwards use an eraser to clean up the picture and refine the drawing.
