As a concept, I prefer this one to the other. Because it shows the strenght/weight of christianity upon her while she seems to endure it with complaisance.
So aside from all the drama on your other nude version of this, I like both of the cross ones. I think they have two completely different feels to them. In this one she seems closed off (well body language wise she is). upset, ashamed. as in the other she is there for all to see. take her as she is, she bares it all, literally and figuratively. It may be more than your intention with these shots, but in any way, these are beautiful captures, as well as the rest of your work.
