Speaking of conventions, I'll be doing commissions at Baltimore. I charge $20 
for a black-and-white image, $40 for color. Color requires me to take the piece home and color it on my computer, since I color digitally. Here's a fine example of that, a Ms. Marvel piece that I did in San Diego and then brought home to add some color.
I actually posted this days ago on my Twitter feed. Twitter is so low-maintenance that it's easy to get stuff up there fast, as opposed to here where I feel compelled to write complete sentences. What? You're not following me on Twitter? Perhaps you should.
