It is indeed, a lot better, and for probably having atleast 4x the ammount of polygons, I would assume it would.
It does look cool, but I don't think it would be worth it to compromise about 300 KB's for a model that is relatively the same to a model in the game.
But it is your request, but I would still suggest you ask an animator to re-animate it for you.
I know of a location of a Footman-style of Blood-elf with a sword, and a relatively low filesize if I recall, if you PM me I can get the URL for you, as I wait in the chat for an admin to get on to see if I can post outside resources, as long as I give credit to the maker.
Sorry for the long read
