I seem to be a slight bit confused about this image...part of me sees some expression of the "really", then on the other side, there doesn't seem to be the expression of the "really?"...I guess I want more of a story....perhaps what is making her go "really?"...I feel she could just be looking up, perhaps not quite questioning reality as the title suggests...This is of course my opinion...and by no means am I an expert!
It is otherwise a decently taken portrait of this young woman at hand!
