Student cartoonists as well as professionals should always be careful that they're not doing a cartoon that already has been done.
With a standard editorial cartoon, you're taking tons of information and synthesizing it down to a single bite - a single moment in time. With animated editorial cartoons, it's more storytelling.
Be happy that you're growing older, that you're maturing, that you're smarter, that you're wiser.
There are a lot of really great cartoonists out there. It's nice to be thought of as one of them.
