Little study, trying to push my speed. 4.5 hours from start to finish. Found a set of skull photographs from the internet, used those to setup a simple scan in Reality Capture. Cleaned up the scan in Zbrush and broke the jaw into a separate polygroup. Used PolyReduce and AutoUV in Houdini, with some UV cleanup in Max. Baked in Marmoset and textured in Painter.
