Is purple a common dwarven color? I wouldn't know but I like it. Picture could be a little clearer, though I am not one to talk about bad pictures. At least the minis in your picture look good.
I don't think Confrontation minis rank. I think you buy a blister, and that blister is your unit.
I think the bases are fine if they are gaming miniatures, as you want your commanders to have the really funky bases.
Only a 6 from me though, as the picture could be larger/clearer.
