Scampy - My favorite design, concept-wise, of the group. A plasma ball among fish and water molecules.
Paras Hilton - My favorite of the angler fish entries by only a bit, it's final design has just the right balance of cute and scary along with looking mysterious.
CyzirVisheen - Giving the angler fish concept a new spin, this one looks just a bit too bulky and defensive for my tastes. It looks great for what it is though!
Cartoons! - This is an odd one. I for one liked the original eyes, as they gave it an air of inscrutability that the other eyes lacked.
AragornBird - Yep, this one will probably win. The electric shrimp is brilliant in more ways than one, and while not my favorite, it will at very least make it to the second poll.
Yilx - Good, and certainly the best jellyfish, but a bit "mage-y" for the ability to be customized to counter anything. It looks flimsy and very special-oriented, but it's a solid design overall.
