A wallpaper version of a cover art I did a while ago for author Howard W. Lewis http://authorhwlewis.com
You can find my process here on my sketchblog (tumblr) http://fantasio.tumblr.com/tagged/Daedalus-rimes
This one was fun as it involved sculpting, (yeah physically!), photography art direction and digital retouching.
See below some images of the different materials, the model is Matthias and was booked for that commission.
Btw. now it is official: I will share a booth with Howard at the Comic Con in San Diego 2013, so probably a chance to meet some of you guys there in person
