Congrats on your position! This is a very sweet portrait - very well composed. I'd maybe be tempted to play with the levels a little more, especially around the skin.
Congrats on the Top Ten finish! This image caught my eye immediately - it's very powerful. Love the pose, the emotion, and a very good use of negative space. Very, very well done :O)
The weighted composition is a good idea, I would have do it in a portrait frame instead of a landscape, with the empty space above her. I think that would work better with her looking up to God.
This follows the general rule of off center subject, but I think the white space may have been better above the girl to give a feeling of a higher power.
