I have created canvasses based on three pages from my graphic novel (the cover and pages 29 and 30). I was encouraged by members from the Peter Salmon Art Centre (PSAC) after they saw the Khentopia graphic novel. The three pieces are currently on view at the PSAC gallery on Main Street in St. Martins, New Brunswick, Canada.
I have not found a gallery near my domicile in the US that is interested in showing my work, so for the moment I am not pursuing this further.
Another larger form of art is the film poster. Here is the one I created for Khentopia (similar to the book cover).
