Great quality, variety (I love the creativity on some of the alternate colors), and animations. Both standard fare and some pretty exotic mobs, I look forward to getting to put these to use, hopefully in my first project.

The big bats do look just a touch odd next to the others (I can't put my finger on it exactly) but I still like them, especially the four ones that look sort of elemental, and the little bats are pretty cute, so ultimately it's all great.
