Stuff like this may seem (and it probably is) simple but I think warcraft 3 is lacking a lot unit model variations (especially original wc3).
May I suggest trying to add new animations though? Where possible only, not only to this archmage pack but in general.
For example, I'm a total noob at modelling but I experimented a bit some time ago and gave the skeleton warrior the sorceress' channel animation and it made it float in the air, bones ripped apart a bit, making it look like it was being tortured by a spell by a powerful mage.
If you could keep a keen eye on things like that it would be incredible!
