Nice to see you finished this. The head came good looking, well better then mine. I love how you made it. Althought, the animations from Rexxar don't really fit, the mesh is far too skinny to be rigged that set of animations. The mesh moves really wierd in attack animations, legs and arms especially. The stand animations are nice and fit very nice. I like it how she holds that axe on her right shoulder.
I think if you mix between some animations you could get her some nice attack animations, with both her hands, like she has now. Look at the Sentry's animations, you can edit that attack animation a bit (just by adding new bone for the weapon/axe) and then you can transfer that animation again but with reverted bones and get a second attack animation.
The animations from that goblin hero model in the mpq patch has attack animations that will fit this model, but the problem is the same as the Rexxar's bones/animations. Their meshes are way bigger than your model and will have clipings and wierd movements when you rig them to the model. I tried and I got same results as you have now, way too wierd movements in the mesh.
