1) Worlds & Wonders. Art of Aleksi Briclot
A beautiful book. And plenty of images. A good review of Aleksi's career(twelve years)

2) Light & Color: by James Gurney
Because I'm an illustrator and This book is a bible for the realistic painters.

3) Framed Ink: drawing and composition for story tellers
Composition is so important in pictures. I don't have it yet but it will be on my desk soon that's sure.
