I don't quite see how a nude female necessarily connotes "lust." While the viewer may or may not feel the emotion by looking at her, her pose is not lustful, nor are her surroundings lusty...It's a fairly modest pose, and you cannot even make out if she has an expression of "lust" on her face...

IMO, this shows what one would lust after not necessarily the sin/act of lust being committed.

I agree the picture is open to interpretation. The subject could exhibit pride in her body for example. Lust depends on personal preferences, cultural norms ect… I tried to pick a nude form with softer surroundings, like the bed / sofa and window at night not in focus to portray lust. I didn’t want to show the face to create the feeling that this is a stranger. I also didn't want to make it overly provocative. I appreciate the feedback and see how I could have used facial features and setting, maybe even lingerie or candle light to create shadows and a more a lusty atmosphere.

This is an amazing example for lust! I love it author! In my opinion you did a good job not showing her face and just a little of her body, it shows that she knows what her sin is and she doesn't want to show her face for it!
Classy and well taken!!
