I don't know anything about graphics or stuff like that, but I do know which graphics look good and which ones don't (in my opinion).
All I know is 2 people were given a stock and had to make a creative manipulation of that. In my opinion, Tackleberry did that better than firefly. Tac integrated the stock into a whole new context, which impressed me. Then again, I don't know anything about graphics stuff, and how hard it is to make something. So all I know is Tac's impressed me more, that's why he get's my vote.
