I'm just doing concept work for this book project for this dude to take over. It's him and his wife's baby, the company I work for is publishing it and I help out most projects we start up. Meeting him tomorrow.
On the technicalities. Yellow Owl over there was done in sketch club, the washed out one was done in Adobe Ideas. The other two were don in sketchbook pro. Now that there's a higher res version of it I'm using it again.
