very nice Trevor! did you remember to turn the thermostat down to 62 for this shoot?
my first instinct is to suggest dropping the highlights just a bit, and I guess its easy to look at a picture and say "its too dark" or "its too bright" and leave it at that...but without toying with the photo myself, I will attempt to articulate what I think might help here a little. I use Lightroom so...that's the numbers i will be referring to.
I would start by dropping the highlights a bit. not much. maybe 10-20.
then, counteract that small overall brightness drop by upping shadows maybe 10 or so, and white maybe 15-20 or so.
I might even drop the contrast 10-15 and see how that looks.
and just for my own personal taste, I would even drop the black 30-40 just to accentuate the beautiful line of shadow down her back and legs.
overall, as usual, a very nice shot.
