It is me for all of them, I just screwed around with the faces and proportions to differing degrees. I need a girlfriend, if only as a reference model to save me time!
I'm not surprised, really: people on Deviant don't seem too hip to the Drabblecast in general. Then again, most Drabblecast feedback never reaches me. I try to make my personal stuff as nice as I can and then send it in to a vacuum. Ditto for the episodes I assign to others. Vocal folks such as yourself [and Norm when I forward covers] make up the majority of what I hear back. No exaggeration. So double-thanks!
Man, these covers are flippin sweet holmes.
