This was a retopology part of a 3d class, though I went ahead and tried to do the full work and baking the normals into the low-poly model. You might notice some of the the images with the textured low-poly look different, that's because on the ones without those odd lines I tried to mix the normal map and a bump map into the geometry in an arnold surface material, but I couldn't get it to work too well, so the ones with the lines around the face just has the normal map.
