Are the head textures very different, or are they too identical? I'd probably be more than a trifle miffed if I bought two separate textures to find that they were nearly identical, but I don't think I would mind so much if it was just the body texture that was the same, perhaps with the colouring adjusted to suit a different head texture. That's my gut feeling... I must admit I have so few commercial textures that the issue couldn't possibly arise for me.
