How do you do the lines so cleanly?
The proportions of the characters and the posing is the best I've seen in a while and something that is often overlooked.
As advanced critique is encouraged, the only thing I found was the long-haired battle-cat near the bottom left.. her head is bending back too far even for someone very flexible. But that's all I could find, and the stances and creative angles and positioning is alot better than most professional japanime and manga. Trust me on that, as I do adore my anime (opening an anime store in bout a month! ^^)
If you do draw at a fair pace and you do not animate professionally, I would suggest it as I've seen alot less skill get taken fairly far
