Sketchbook - christian theme

I have started a new A4 sized sketchbook for my art classes which we share on their forum. So naturally I created one with a Christian theme. It will be fun to dedicate an entire sketchbook to one theme. Many of these will just be quick concept sketches exploring a theme. Also I plan to do additional side projects on this theme, utilising 3D visualisation software such as Blender and 3DS Max. Also practicing digital painting on my graphics tablet. I am completely new to that but it will be fun to learn and to develop concept art.
