Well, I've posted a modified version of my original. I would like your opinions. I've played around with the lighting as Cake1 had suggested. I've also darked the drape upon which she's kneeling in order to avoid drawing the eye away from the subject. I did this based on Steve Stahlberg's composition tutorial that Stewer & FaceOff mentioned. I think it was definatly an improvement, (although you wouldn't think it would be necessary considering the subject - hehe).
Thanks everyone for your help and input. Please feel free to let me know what you think. This has been a very informative thread. Keep it going.
