Here are my concepts...
|The White Forest.|
How the forest is when it's undisturbed. A blank canvas.
|Carl's Painting Forest. |
These are digitally painted but would be hand painting for the final animation.
|Simon's Sketch book Forest.|
Again the shading of the trees will be hand sketched. This style
includes a sample of da Vinci's handwriting across everything...
|...As this close-up shows.|
To give an idea of how these settings might interact I've made a short animatic to show the changing. There are two styles in the same video to see which would work better. The first 10 second shows the idea of the trail... only the specific area they've touched changes. The next 10 second shows the whole forest transform after them.
I also looked at a coloured forest... completely green, to give another style for the studio to choose.
