Yet another great art piece! It reminds me of "The Iron Giant". Granted, I've never seen that movie, but I've heard a lot about it. Titan concepts are pretty cool. Maybe that was the inspiration for the iron giant? I just loved all the little things going on in this picture.
The hot air balloon is probably the best part. Everything just seems so evenly spread out. I think there are starships in the sky. A little low flying, I guess. The rock on the left looks like it has a maze on it.
