The pikachu version of the ad is my personal favorite.

The Sonic version below is my 2nd favorite. I wasn't sure whether to make the "s" part of "Games" black and shorten the nose graphic or leave it as a  peach color over the nose. So in the end I went with the latter decision. I sure hope it looks good that way.

Next is the Princess Peach version. It's not the best visually, but the call-to-action was certainly great.

And lastly is my Princess Zelda ad. I'm thinking about making a Tri-force version as an improvement to this later, since the typographic image of the princess looks ugly.
