The pose and the idea is actually not bad. Lighting, exposure and composition, however, need work. The presence of the carpet and baseboard is distracting, and doesn't add anything to the image. Also, on my monitor at least, the picture is very dark with very little detail or texture (sorta muddy). Try this one again with a neutral backdrop (and even some experimentation with lighting) and you could have something really interesting.
This has soooooo much potential. I love the message, the title, the pose. I'm not a fan of the lighting, background, or foreground. I would love to see this exact image shot on a black background with a keylight that highlights the cross and really drives your point home... You've inspired me to play around with this theme.
Interesting idea. Could have been executed better if the background was a solid black or white - that would have emphasised the subject and pose better.
The lighting here is very flat and uninteresting. More use of directional light putting the subject in a pool or more side lighting could help improve the image. The skin also looks like it has been through Neat image or something.
Technical issue with the lighting.....your image appears dark/underexposed on my monitor. I think adjusting the levels/curves would make a great difference
