I have been looking at some of the mini's available and they look really awesome, are they a comparable scale to warhammer models as i would be using them for warhammer roleplay?

Warhammer minis are smaller than the Anima Tactics one. Warhammer (fantasy minis) are on a square base, Anima Tactics on a circle base.

But if you want to use the minis for Warhammer RPG, I don't think these differences are important.
