Interesting. Personally (as a fan of some
of the Tome of Battle) I personally see this more as a school of martial maneuvers, but I understand that that's not everyones cup of *beverage of choice.*
All in all, nicely done. I like the fact that the damage you can add is just enough to get the flavor across and not enough to actually become an attack, by the way. It adds some cool effects without overpowering the class.
