At practically every level, the way I make comics is an act of improvising within structural boundaries. There's a rough plan, with a beginning, middle and an end, but how I get from one point to another is unknown at the outset, and a large part of what keeps me engaged. It's an exploration for me, and hopefully for the reader as well.

It seems to me that any popular fictional character's appeal is idiosyncratic in nature. Characters with large followings - Sherlock Holmes, Harry Potter, the crew of the Starship Enterprise - seem to embody something very particular even as they speak to something within a huge number of people. When I think of the most time-tested examples, the common thread appears to be an author who feels deeply for what he is creating.

I try to be as faithful as possible to the facts as I understand them, but any story is at least partly a product of the imagination. I can comprehend a lot by immersing myself in all of the information I've collected, but my imagination is what brings it to life, and the bridging of that gap - between the received history and the conceived fiction - is both the most difficult and most enjoyable part of the process for me.

I love writing and the little filmmaking I have attempted, but comics is the means of artistic expression that feels most comfortable to me. It's also still a largely uncharted medium with enormous unrealized potential. I like finding new ways to communicate an idea or a feeling, ways that can't be duplicated in other media, so I take great pleasure in the invention and exploration that comics necessitates.

While we can generalize when describing a given medium as hot or cool, all media can be said to possess both hot and cool aspects to varying degrees, and part of what I try to do with comics is figure out when and how the temperature needs raising or lowering.

We are apart and alone, as we must, but at least we are alone together.
