Hi there! This is a nice photo. There are so many things I like about this photo.
First let us start with the model. Her pose is a sensual one and the expression on her face only adds to the mood. The ruffled look of the hair adds to the sensuality too. The white background is an interesting choice and in itself, is aesthetically pleasing. The white bed sheet goes well along with the white background. This leads to the viewer focusing the complete attention on the woman.
That being said, there is one thing that bothers me about this photo. The shirt that woman is wearing is white and her hair is not very dark. There is almost a blurring of the lines between the woman and the woman's body. Whether this is deliberate, I am not sure. Maybe the contrast can be reduced to remove the some of the brightness.
Apart form that, nice photo.
