I see some problems with it -- team color ''tc'' is missing, the tigers claws are not alpha channeled so they appear as big black rectangles rather then actual claws, and there is a wrap gap on the tigers upper forward shoulders as well, an easy uv wrap fix if you move one set of points just a tiny bit off to the side to match them up better.
the animations are very smooth, and the warden her self looks pretty good.
spell animation could be more interesting, but blizzard models are hard to re work like that as I know from my night elf villager.
you could add another variation with team hero glow on her origin and her weapon. to make a more colorful hero variation.
short of the claws being my biggest problem with the model this model looks real nice actually well done. 7/10.
Edit: the model viewer displays the claws incorrectly, my mistake, the claws look real nice. could be bigger/longer though.
another suggestion I thought of, perhaps an animation involving the tiger getting up on its hind legs and swiping at something. a thought. =/
