I read an article earlier this week, about how people are scrambling to visit the quickly defrosting frozen tundra to see the polar bears before they go extinct. That made this a fairly obvious direction to go in. You'll notice I made a few type modifications from the rough version. I also added a guy (driver?) jumping from the front cab. The bear was also previously just sitting there, but I thought to add some action, I'd show him either climbing in or getting ready to climb down. I always try to show "some" action in my cartoons if possible. I like to motivate the viewer's eye to move around.
Here's the rough:
I'll probably post one more syndicate cartoon later today.
