Amusing collection of creativity. Those character are all awesome, and pretty unique, especially the center one. Al the funky emoticon outlines in the background are a nice addition, and I like the fact that it's all centered on a canvas. My first though is: those should be made into Pokemon, hehe, but of course there are far greater potentials! The eye is a bit bizarre compared to the rest of the image (which is all really happy and carefree) but all of i's good art. Keep it going!
