That would be awesome; and I definitely plan on continuing to help Civitar with his Warhammer art.
For the Qunari units; yeah, basically every unit up until the Renaissance, minus the musketman and the cannon, I would want. Simply adding horns to the vampire swordsman model, and maybe making the hair white and greying up the skin would be all that's necessary.
However, if you do want to go above and beyond, then I suppose for the units of the ancient era, having them look like this guy (no armour waist up) would work:
And then for Classical to Renaissance, using the more armoured ones would work great as well:
I suppose as far as female units go, the Tamassrans; their priests/teachers are female, so It could deffinitely work for their religious units. Here are some references if you need them:
And then for UU's, I was thinking the Arishok; a combat-capable great general replacement. (If need be, I could probably find a good .mesh file of his in-game model from Dragon Age 2, if it would help).
and then the Dreadnought; a powerful ship;
And then eventually, I want to get to a total-conversion mod that contains mages and templars. In which case, their mages would look like this:
It is a LOT to ask, I know, but I think it would result in an amazing final product. As I said at the top, I do in fact plan on continuing to work with civitar, and whenever you need any 2D art; just let me know.
