PhotoShop is a program I use all the time with my 2D stuff. And that's an extraordinary program - you really can do anything there, and I've never hit my head on the ceiling. The 3D stuff is incredibly complicated, monstrously complicated, but for the things that I want to do, I've found very simple and interesting ways, I hope, of making images without getting tied up too much in the maps and technicalities.

Usually, the most difficult thing to do is photo-real stuff. Something that has to actually look like the real world, because it's just so difficult to do that. We're just so used to looking at the real world, our brains instantly see when something is not quite right.

I tend to be known for different things. I mean, there are a lot of comics or sci-fi fans out there who sort of think of me doing that kind of work, but there are just as many people who like the CD covers I've done, or the children's books I've done. So different people like different things.

If you want to be a chef or a scientist, you've got to know what the current thinking is, so if you want to write comics or draw comics find out what the very best ones are and look at them all and then you'll know where the bars are because the bars are often very high, if you are going to make a splash and make yourself known, you need to get to that level.

The inspiration is all in the script, in the text. So whatever it is, either it is a film or a book to be illustrated, anything. Everything you need to know is in the text. So the thing is trying to find right tone and voice, the right style, the right way of expressing the emotions in a story or in the location of the story, but it is all in the text.

I've always used masks. I think it's a lot about the fact that masks often reveal a sort of subconscious element to a character. The mask is carved and given an expression or markings to reveal something, even though it's shielding the face. Even though it's hiding the face, it seems to reveal something underneath.

The reason I love comics is that they DON'T move, and there is NO sound. As a creator I have to evoke those elements in the drawings and writing, and the reader has to create those elements in their own minds.
