Cute! Not bad for a first try :) The background is nice, dark & gritty, which suits the look on her face & helps to town down the cute factor ;)
Personally I'm not keen on the slice of her face in the centre of the image. It stands out a little too disjointed. I can see what you were going for, but it detracts from the girl herself. And perhaps the text is a little too bright & stands out too much. Perhaps if it was a little less opaque ~ but all that comes down to personal preference ;)
Otherwise it's a great litle wall :D
