How did I get on THIS poll? Anyways, for me it was between RayquazaTheKip's and Locopoke's. Locopoke's looks like it has just wings attached and a recolor (although it probably took more work than that), and there doesn't seem to be that much Muk on there. On the other hand, RayquazaTheKip's evenly mixes all three Pokemon evenly and the colors and fusions are more smooth and it looks very interesting. The other two look a little weird to me.
Again, take everything I say with a grain of salt (I'm not that good at critiquing stuff, I think). I just say stuff because I feel like it.
@Rodan: When were you going to put up the polls? If you're too busy or something, then why can't someone else just put up the polls?
