I guess with it being such a lose sketch I can't quite distinguish what is going on there.
@JessicaLinnEvans I think you need to add more shadow back in.
Right now, there's a good chunk of realty given to the lightest value, and at an almost white, you're not going to give yourself room to add color to white.
If it is night, you would be best to have an average shadow as your main value, and then add cast and occlusion shadow from there. Once you've done that, I would add in your average light values, your reflective light values and only small spots of your lightest value.
Also try to think of the plain changes as you work your values in. I can see that you have light coming from the bean under the pillow, but the light seems to go through the pillow rather than around it.
You could consider making the room taller, and have the raven sit perched higher in the window so that the light will project towards her face putting emphasis on a diagonal eye line from one focal story feature to the other.
