The small number of presets didn't seem jarring to me, until I reached the Tiefling camp for the first time. Half a dozen faces don't go far in a crowd. I felt the same in the Goblin camp too, and can't help but think that Moonrise Towers will be full of cookie-cutter Duegar and Drow, and Baldur's gate will be home to yet more Gingerbread men - stamped from the same cutter with only limited icing to distinguish them.
