Nature is always interesting, and Nature Science Journal certainly lives up to that. I mentioned that I work in many different ways, depending on the brief. Nature have almost tested me to destruction over the years. In the very first issue I worked on, I did two pieces for them that were completely different. One of them was the Many Worlds cover linked below. All the lettering was hand drawn, including the small print at the top, to get that authentic pulp mag feel.
So, I get to try different things and I enjoy it! I don't always succeed, but it's always, always interesting. The classic request was, "We want a Holbein. We need it Tuesday." It's here, too, if you're interested.
