Those of you who've bothered to read my ramblings in these descriptions and journals know that I believe I have a problem with the speed I complete drawings. I'd like to do sketchbook commissions in selected artist's alleys, but was concerned about (1) encountering really exotic (or weird) characters that I'd have no clue how to draw well, and (2) being able to complete sketches in a timely manner, as evidenced by my dead-dog-party sketches.

I've been reading a book I bought at C-ACE, Simplified Anatomy for the Comic Book Artist: How to Draw the New Streamlined Look of Action-Adventure Comics!, and while on initial perusal during the con, it looked like stuff I already knew, but something told me I might still learn something from it.

While I can't nail down any earthshaking revelations from the book (in a nutshell, it deals with the type of superhero art you might see in a Teen Titans comic book, (animated-version style)), I've taken some inspiration from it, and turned out three pictures since reading it. (actually four, as my entry in Arctic-Sekai's contest was done after I bought the book, but I hadn't really studied it at that point) This sketch is the latest I've turned out since re-reading the book, and is noteworthy for one reason:

It took only 35 minutes to reach this point

If I can maintain a pace like this, I might take a chance at an artist's alley table sooner than I thought. Of course this wouldn't be the completed image--even if only asked to do pencils, this would be cleaned up and sharpened, probably an additional 20-25 minutes of finishing work.

With all that you've read above (assuming you haven't TL/DR'ed), what would you consider the going rate to be for a cleaned up (I'm talking pencils sharp enough to cut yourself on) sketch at this level of skill, and how much more for an inked version (most likely with brushes--you can see my other submissions for pics inked that way)

BTW, this pic will be completed and colored, as it contains a few fashion elements I've wanted to incorporate into a character pic for some time now.
