A colourfully emotional picture. The first most noticeable thing to point out are the females socks. The different colours, they really contrast with each other and are really cute, which also brings us to your toy bear beside.
It looks cute, yet depressing. It leaning towards the girl makes it look as if the bear is waning for her, or her childish love and affection.
The background looks like a bed-sheet set up, also gives it a sleepy look, also reminds me of an asylum, which is another symbol for loneliness and depression.
Overall, it's unique is a common way. It's also cute in a depressing way. You get the best of both worlds with this piece. An overall favourite of mine.
Fair to say, I like the shot pretty well as is. The suggestions I have come more from the post processing side of things and from the angle of execution. I'll cover each in separate paragraphs.
The contrast in the exposure seems pretty well to me, even though the highlights are a little more muted than I would like. I believe I'm seeing a little bit of a cross-processed style with some magenta added to the shadows.
On the post processing side of that, I'd actually like to see more of it. If you use Photoshop or a powerful image editor, I'd say keep the exposure about the same as it is now, but bring the shadows up to make them appear faded. That may reveal a softer side of the photograph, rather than keeping the light so harsh between the bear and the blue sock. Piggybacking on that, push a cross process into it a little more. Add a touch of magenta and maybe a soft, soft green in your midtones to see where it takes you.
My only other suggestion would be to bring the camera a little bit lower. I get the feeling that I'm looking down from knee-level and that the shot would be more powerful if the camera was lowered about five inches.
The pose of the foot -- the delicate lean of the left foot (and the attached symbolistic boy/girl relationship) is wonderful. The teddy bear is great as well, though he seems a little farther back than I'd have thought. Maybe keep him on an even plane with the ball of the feet to cheat the camera into keeping him aligned with the focal points of the image.
