Well, soon there will be! I have been putting together a special collection of images for the iPhone and iPad this past week and just submitted the final set of pages and icons for approval:
Bring inspiration and guidance on how to draw the female form with you wherever you are! "Craig Elliott: Pinup" is a collection of large studies, well suited as wallpaper images. The studies have been rendered in many colorful mediums of expression such as watercolor, pencil and pastel. (31 pages, full color)
My hope is to continue to release these book Apps under different themes, as long as they do fairly well. Keep an eye on this spot for final release dates etc. I am shooting for a Comicon 2010 release!
