Here's the sketchbook from Alan Bay, aka Smallguy, an artist based in Singapore.
He started out creating bitmap video games for mobile phones, later went on to a Japanese company specialising in MMO games, then worked for Ubisoft Singapore, Mirage Studios and AxionLogic. He's now a freelancer doing illustrations, comics and concept art.
This 64-page full-colour artbook collects the work he has created over the years. There are some art for Teenage Mutant Ninja Turtles, pixel art for games, and other character and environment designs.
He will have a booth at 2014's STGCC and the book will be there.
