I have far too many favorite illustrators to mention them all, but some of them come to mind almost instantly: Hal Foster, Alex Raymond, Al Williamson, Paul Gillon, Moebius. It’s not that I try to draw like any of them (which of course would be impossible), but, being optimistic, I think that endlessly looking at their drawings may have some sort of influence in my, ahem, style. Eventually.
It seems that I restricted this improvised list to “already deceased comics artists”. Oh, well. Not my intention.
