Thanks for the comments. I had my finger over 1/2 of the flash, but she had a very light blue dress and she is very pale. Also, she was on a raised portion of the sanctuary, so I had to shoot up a bit.
I think this pic would have better with more courageous cropping. Now there are too much dark and empty space up right. I would have cropped one third from up and one fourth from left. But a great moment have been shotted!
I don't think the lighting is too good here. She and her dress are kinda washed out. Also, her face is right in the middle, so the composition doesn't work that well. Does fit the challenge though.
You have potential. A few things in this picture detract from the main focus. One--the mike. Two--the lighting. Next time, try to top-light the model. That way, you don't get the bight pinpoints in the eyes, either.
Onboard flash has not worked well here (in fact, doesn't really work well anywhere). Quality of the light is too harsh, and casts unattractive shadows. I'm not at all sure about her expression. Background looks like not much thought went into it.
