One of the things I've been trying is different styles, colors, line thicknesses, to see what I can come up with. My very first drawings were pretty much all line, then I moved to full-color ones, and since this past spring I've moved into grayscale images, but one of the cool aspects of the digital pieces is that I can save them and rework them in different formats, so that my original black-and-white drawing of poet Bob Perelman from earlier this spring became a color portrait without being completely redone (though it did take some effort).
Below are a few of the many sketches I've done over the last month or so; I keep thinking that I may have to return to taking the El on days when I'm not so pressed for time in order to keep my practice up. Enjoy!
