Here's one I did for Brother Bear. I was asked to draw the abandoned human's village.
The initial intent of the directors was to make the landscape look more prehistoric, so I added these giant Redwood trees to make the land look more interesting, I also thought it would give the human world a more diminuative role within nature; I wanted these trees to look like skycrapers.
Sadly, they didn't use the idea and instead went for a more straight foward/natural landscape. My job as a visual development artist is to come up with visually compelling, unique and thought provoking images, and I think this one does just that.
