This is fantastic Erica. Breaking 6 and making top twenty on your second challenge is definitely something to be proud of. Congrats and keep up the good work.
I'm a bit surprised that you have received 20 comments and you don't have marked any as useful , I'm quite sure that the people who have taken time to leave them would appreciate that.
It's an interesting photo , you have captured a lovely moment and the lighting creates a dramatic effect.I agree with sanx that it would have looked even more impressive with the ballerina facing in the opposite direction.
In advanced editing you could have softened a bit the light on the right leg , nothing very important as I think that it's more a very impactive shot than a technical one.
Well done , keep it up.
Please feel free to email me about this critique , this is only a personal opinion.
Very nice. Great lighting and composition. The image would be even stronger if the ballerina was facing the camera and connecting to the audience--with a "I'm so winning" expression, perhaps.
