I agree with sno. I don't think I am brave enough to show my sketchbooks because they aren't this rendered or good enough. I am in love with your exquisite work!
I love my sketchbooks because when I look back I can see where my brain was at that point. I can use specific books as reference for different subjects for when I get blocked. The ones I added here are from a sketchbook mainly about owls. A lot of my sketchbook doodles or incomplete thoughts or are just crappy. Those are the ones that teach me the most.
