This bruiser of a commission is just about finished. I have only the red rat-dragon remaining, and I hope to tend to that before the end of the year.
I used Prismacolor pencil and gold paint pen, and the black background is Photoshop for now. I have guidelines underneath that black that help me align it on the scanner bed. I have to scan it in ten parts (twelve, once the rat is finished), then assemble it all in Photoshop.
Final dimensions: 18 x 36 inches.
