I have since added shading to the flower arrangement on the bow, they won't be quite so flat in the final. I have also been working on the background behind the scenes, but I'm going to wait a while before I share that. I may make some changes to the background closer to Hallowe'en, but I'm finding the image to be extremely bright, colourful, and cheerful in my working file.
It makes me wonder how I'm going to top it for the winter holiday special!
In case you missed it: part one is here and includes the pencil, digital line work, and flat colour.
