Deadly Brew

I wanted to explore some different computer illustration techniques using textures and blending modes.
Started with a very loose sketch, then I started by drawing/painting in the room; just blocking in the shapes and values. Then I added the shelves and items around the room. Finally texture, colour and finishing touches. This image took approximately 40-60 hours to complete. [no client; no time clock ;)]
I do a lot of work completely in black and white first, then add colour. This image I also did that way except for the witch and the cauldron. Not sure why.... just did.
