heyas; no, they're not lower res, but look at the map.... notice how much bigger the head is compared to the body. so for the head, you maybe have, say 500x500 pixels to paint the face, while the whole body has... maybe 500x300 pixels. now look at the figure, the head is smaller than the body, right? :) so the small head gets 500x500 pixels of detail, and the whole body, which is bigger, gets barely any more texture real-estate for its details.
