Here's one of the fully illustrated backgrounds featuring Zenopus' tower and the city of Caladan for the animated version of last fall's radio play. This also gives you a general idea of the feel and mood that the background images will have.
Again I tried to simplify and stylize the background just as I'm trying to do with the characters which is always a challenge for me but it's a great practice to loosen up my drawing style.
I've included the original sketches that started with a more realistic approach and ended up with the above image.
I'm still working on animating the final shot of the first scene but it's coming along. I should have a clip to post soon.
