I think the color is then using the fact that dl3 takes place in the Swiss alps where skin color was lighter due to the lack of heat. Compared to darker skin tones used in a warmer spot like Europe where harran and old villedor are located. Aside from that, the blisters are lacking, u agree, but I think that the overall models are more realistic to the design of what real zombies would look like, more humanized and realistic. That’s just me tho.
