I choose three. 2 tries to be funny, but really isn't. One is a little abstract, it has the word "advertisements" in it and has some semi related words in the background, but has unrelated otherwise.
1 is invisible but when I put in the address in the address bar and saw it I thought it wasn't that impressive, 2 is a bit cute and silly, and 3 is funny but I don't like the hair do for some reason.

I was about to pick number one because the banner was anime-related-- or else why is zomganime not an anime website?-- but the problem was it's supposed to be an advertisement. You don't go putting that it's an "advertisement" on your banner. So, sorry, I couldn't go with number one.
