Very cute however I don't like the background. Even though it's not in focus the wood background still has a lot of detail that draws attention back there.
I will vote this low because the challenge specified a "studio" shot and this is obviously done outside in the backyard. Cute picture but it doesn't meet the challenge criteria. ;~(
Beautiful girl , what a lovely smile , what lovely eyes !
I don't like the background because of the shadows.You should have tryed to use a different lighting or at least have placed a white board to avoid shadows in the chin zone.
Not sure why, but the top of her face is a lot brighter than the bottom - like maybe the flash or strop was pointed at a slight upwards angle to the subject.
