This sequence is part of some exploratory design done for an animated children's film. Step#1: The Castle. I wanted to avoid the round towers/pointed roof style of Disney. I started square-edged and sorta' Romanesque and then it started growing until I had a medieval hill-town. I added a rolling-hill landscape and where it intersected with the default ground plane, I suddenly had water and a shoreline. That begged for ships and off-shore rocks...and a harbor for the town.
The tale was written, and takes place in the 1880's...the heyday of fanciful heavier-than-air flying machine design. But proto-dirigibles were getting off the ground, and hot-air balloons had been around for some time. I urged the inclusion of flying machines as a everyday, normal-as-birds-in-the-sky event, and, where it would not contradict the storyline, used to ferry the characters on their travels.
This post is two seperate renders, edited together. Thus, in the second half, with Bill's multi-colored balloon, the ground is much darker.
