Okay, so if you only know The Dresden Files by the television show, or if you just know it by the comics rather than the books they're based on, this might seem a strange interpretation of Karrin Murphy, the cop buddy of wizard Harry Dresden. This is how Harry sees her, when he's viewed her with his Wizard's sight (third eye). An avenging angel.
Hand drawn, then colored in PSP. Which only served to remind me that I'm MUCH better at the computer aspect than the sketching, in the end. Oh well.
I don't know, I think you're darned good at the sketching aspect as well. It's already well established that your digital painting is outstanding. Although I'm not familiar with the Dresden Files in any media, this is good enough to make me want to read the books and comics and view the TV show too! Excellent job.
