Quick thumb nail sketches: Concept drawings (Baucis)

Using line art and the brush tool on Photoshop, I quickly drew my ideas onto each thumbnail:

Image 1: "Lost above the clouds support the city"
Image 2 + 3: "When the days are sunny, a pierced, angular shadow that falls on the foliage."
Image 4: Shows image 3, but from a distance resting on the clouds.

Italio Calvino, describing the city Baucis.
