This is a wonderful capture. Some may not like the lighting but I think it adds to the photo. Only shadow I think distracts is the one on the wall. Good job. BTW - she does not look all that excited about giving the teacher the apple! LOL
I could be wrong but I think if the light was coming from a different direction than below it wouldn't have such a creepy feeling. But if thats what you are going for then good job...
it would really help if there was even just a hint of a smile on her face, alternatively the look would go well with her handing over a number of papers implying that she had done her lines (or similar)
You surely don't look very happy to be giving that teacher an apple...actually it looks like you're getting ready to hit her in the back of the head with it.
Nice detail, to make it better, use a gray card and reflect the light into the face to bring just a bit more of the left eye out.
It will keep the effect you are after, just make it better.
The composition is nice, but I don't care for your choice of lighting direction or strength - it's a little dramatic. That is unless this is a poison apple....
