In my OGR feedback, Phil pointed out that if I were to have a simplified art style for the 2D aspects in the 3D space, the style of the life cycle should match. He also noted that the use of a boy scout is quite a nostalgic idea and so a 1950s style would be suitable. I have looked at some of the recommended styles and have found some more pictures that share the styles. As you can see, they are very clean and neat, with line drawings with a some blocks of colour. I think the style is similar to that of my life drawing style of smooth lines and there not being a lot of detail. The cycle should, therefore, transition smoothly and the cells should move accordingly.
