Experimentation 2 - Black on Black

My version above tweaked in Lightroom from a photo taken in AV with -2 stops of exposure compensation: the darkest in the extras.  I'm wondering if it's too dark still!!  Needs to be seen in Large!!

The extra is the results that show that a photo taken in Auto or even in AV tends to be too light and needs to be darkened in camera with exposure compensation.  (or some other way?)

Yes I'm spending far too long on the computer!!!!
