Yup, bump map is indeed lower resolution (1024x1024) than diffuse skin texture (2048x2048).
It would be better to use higher resolution one, but these were the data I had at hand.
I also made a quick-and-dirty 2K gloss map so it should help a bit with adding surface details even if bump map is lower res.
Gloss variations give surprising amount of surface information - in another demo at one point of time I had bugged bump mapping and it took me a while to realize it was broken because gloss map was working so well.
