It is a little unfortunate that the culture here seems to be a lot more about supportive praise than real criticism.
I also have problems with the shadows ... the bed is casting shadows, but the girls aren't casting shadows at all that I can tell.
Shadow from the headboard appears to be cast from a light BEHIND the wall...
Shadow from the baseboard is cast by a light at maybe a 90 degree rotation from the headboard light, which is really, really weird, seems like you have it lit something like:

..bed...

Brass on the bed is a bit too bright, you might play with whatever material you're using to get it to emit less light.

You may want to try to get the lamp to actually act like a lamp; while the image I'll put here is pretty messed up, e.g. the cloth is awful and the light's a bit green, one thing that comes across pretty well is the payoff for trying to make your light come from a real light source in the scene:
