I hope you don't mind, but I downloaded your image to get a better look at it and played with it a bit.  I've attached my revision for your interest.

Lots of good data collected in your Horse Head image, and I think a lot of good data yet to be pulled out of the shadows in the original raw image...

OK bwa, i see more details on your pictur but also more noise, may be due to sharpeness operations ?

It is difficult to enhance a jpg image...
