Well just started this Critique club thing so lets see how it goes, hopefully you like my examination of your picture :)
Well for starters what we have here is a decent picture so there is not very much I can say about it. It is very good in its simplicity and the girl is looking like she liked her present. And the lightning on her face looks good.
I must however say that there is something that is missing in the picture, something that says that *whooomp!* that I like to hear when I look at a great picture. If you would have made this picture just a litle more exciting you would have been able to get a higher score and I would have heard my litle *whooomp!*
Well hopefully this comment is helpfull for you :)
Nice experiment and the face is well lit. Took me a litle time to figure out the box and I think maybe there is to much negative space. Also I think that the face is litle to much sharpened. Fine image though.
Okay....with a small "kicker" light, or back light this could ahve been a fantastic image. Have a small back light helps separate your subject from the background, which is something this image definately needs to be killer.
