Sculpture Reconstruction

Over the past few years, I have been playing around with constructing faces over natural or cast human skulls.
I have many years of experience  sculpting  figures but have never seriously tried to model over an actual human skull.

I suspect,my main concern is it would be too restrictive and what really would be the purpose of such an enterprise.  I thought it might be possible to arrive at unique looking face but in the back of my mind,I was concerned that it would end up looking generic.
This particular specimen,that I was considering has a long narrow face with an exceptional length to the cranium(185mm) and a long projecting nose. I thought it would be sensible to consult texts on forensic facial reconstruction during the project.

 The buildup of the face was very gradual as I wanted the skull to have as much "input" as possible. There were many revisions throughout the entire process but unfortunately, I didn't record them. Next time.

The finished work does have a unique face but I'm still unclear as to what this bust is actually about.  I have  made over the past year four different reconstructions but none of them work as stand alone sculptures. These pieces seem to be leaning towards an installation format. I not sure what the next move is other than to press on and make more.
