If you're learning to draw (whatever that means), Nina Johansson's sketchbooks will either make you squirm with awe or inspire your pants off. For me they did a little bit of both. And she also has a blog.
As frustrating as observational drawing can be to master, it'd be nice to pull my imagination straight onto the page - no compromises (such as hands having to be in pockets or behind backs).
Out of curiousity, who out there keeps a sketchbook? In three words I would describe mine as erratic, unfinished and dirty. How would you describe yours?
