Making progress on the coloring book project! The concept I've settled into is to offer each image at varying levels of complexity.
Example sample here is the three headed dragon...which is what I thought Tiamat was, until I looked him up (he has five heads). Anyway, you can see the three levels of complexity that will all be included in the book, hopefully appealing to the casual colorist and the dedicated details type as well. They look pretty sharp when printed at full size (11x17) and I can't wait to see what people color them into.
