Great model, interesting design! WC3's style really is medievalism and in this work you've come pretty close to what would be a Templar crusader.
I enjoyed the creativity in adding the cross and crown to the medieval patterns.
The mounted version I think would be better with another model to the rider or applying more armor. This version also has animations of a mage from a distance, the attack seems slow and a little weird, I think the ideal would be to better develop your animations for melee-attacks or copy some attack animations from Knight.
