John,
really like the B/W tonal range achived in #2 which make the photo interesting to look at.
While probably not your intent it evokes sadness - a drought/starvation/dead animal shot with all the ribs and hip bones protruding .
#1 has some nice lines/gentle curves and I particularily like he balance the extended right arm gives to the shot.
#3 makes great use of the sand and rock texture but sorry think the
model looks more like a washed up copse than an object of desire. The right leg being raised (presumably for balance) looks out of place with direction oppossed to the draped lines
but then perhaps beng a female I see the shots from a differet perspective ?
