This is a sculpted character produced entirely in Blender. There are no textures yet, all the detail is in the geometry (which hit around 800K faces).
I think Kent Tremmel suggested in a tutorial getting hold of a human skull for reference. It seemed to make sense. Found a full size replica on ebay and the spookily realistic artifact now sits on my desk.
While this chubby character doesn't look too skeletal, I started with an underlying structure based on the skull. What have I learnt from this sculpt?
I think the proportions and placement of facial features is better than my previous attempts. I also found better ways of using the crease brush in sculpt mode.I alternated between a higher strength with no pinch for structure and a very low strength with more pinch for detail and smoothing.
I also found the smooth stroke option really useful. It created some lag but the results were far more consistent across the creases.
