I've finished photographing all of my drawings out of my portfolio. Now I'll never have to drag out those huge newsprint sheets. Here's some of my favorites. I have the first 7 hanging in my apartment. All were done with charcoal, except the last 6 that were graphite (pencil). I sort of grouped them by subject, not exactly chronological, but most of them have dates written on the paper. Click the thumbnails to view larger.
Oh, I should note that these are all observational drawings (not from reference photos) except of course Rembrandt's elephant in slot one and the made-up barn in 2 point perspective at the bottom left.
