well, when you ask for critiques i will respond as generally peps around here will not critique on the gallery page...seems to be an unwritten rule.

-congratulations on your new obsession; poser.
-the bed figure pose is well done, however the figure giving the punishment doesn't look like she is moving like she would if she were using a whip...shoulder and torso are not moving forward...quite passive looking.
-i'm having problems with the shadows going on there. they seems funky to me. especially the highlighted bedposts and the rest of the scene...maybe it's just me. upon a 2nd look, you have more than 1 light going on don't you? turn the other lights shadows off.
-the expressions on their faces is non-existant.
-maybe turn down the reflective value on the bedposts

lighting is everything. i think of alfred hitchcock in regards to camera angles and lighting...a master.

keep them coming and good-luck.
regards
