This is a tough award, because while a lot of people vote in it, I don't think all of those people spend the amount of time going through the threads in the graphics forum to make their decision... but they see the badass avatars and sigs made by our regulars and decide from there. DM is definitely a fantastic photoshopper, as are you. The voting just doesn't reflect that, which is disappointing. Sometimes these things turn into popularity contests.
I wouldn't go as far as saying it was due to popularity, because grrl is popular outside the graphics forum too (on AIM) but everyone sees FITM's work all the time. It's hard to vote for someone's work you never see.
