i havent noticed that problem but the one i notice alot is that the edge of the lips is a strong solid line on nearly all the characters whereas it should be a little faded.  Example look at Alice from Aery Soul compared to Nanette from DM or even Adriana from chevybabe25.  And im not saying that they are bad character packs quite the opposite I think they are awesome but I just dont like the solid line on the natural texture.
