While you were away newgrounds grew up
You may have seemed really skilled back in '03 when most of the portol was occupied by stick flashes and hentai quizzes, but now we are reaching the point where alot of the work is professional grade. Take a look at the Yuyu if you don't beleive me (I'm sure you already have, that was just for emphisis). What isn't professionally looking is really very funny (metal gear awesome). If you don't REALLY improve your not going to look much better than the flashes that get highlighted green for a few minutes and then are overcome by those with taste. How should really improve? Well first read the other reviews, they will offer about a million helpful suggestions. What I would like to focus on is a little aspect of humor called timing: When the dwarf guy finds hes being hit on by the gay elf (sorry if this isn't the correct WoW terminology, but you said that you intended it to be funny to people that don't play so I feel entitled to judge) it seems as if you wanted to get it done as fast as you possibly could, so you don't even wait a second to figure out how a situation like that would actually play out. What might have been cleche (sorry about spelling) but still mildly amusing is just flat and uninspiring. Work on timing.
