Story-wise my biggest influences for Heroes for Ghosts are 80's and 90's era X-men comics mixed with live-action stuff like Star Wars and the 2000's Battlestar Galactica. The "Wild Cards" mosaic novel series edited by George R.R. Martin was also a big influence--at least the first four or so. General world history-- particularly that of global conflict, is a big influence as well.
Art-wise my biggest influence was the early stuff by Arthur Adams, along with other high detail guys like Moebius, Travis Cherest, Jim Lee, Neal Adams. A lot of indie guys influenced me too with Gerhard being the most notable. Of course there are also influences from the fine arts with artists like Michelangelo, Albrect Durer, Leonardo, Hieronymus Bosch and others. There are little homages to all that stuff throughout my work.
