prayer.

This is my first photomanipulation ever. I know it isn't perfect, so please give me suggestions on how i can improve... I know that the lighting of both pictures don't line up... something that I tried to correct somewhat. Trying to make the two photos unite in a seamless fashion was also difficult, although aided a bit in part by the use of grain.
The background was a picture I took a long time ago. The praying woman is from *Alegion-stock; the original image can be found here [link]
Hope you enjoy.
