I really like how light and airy this is. The only comment/criticism would be that the lower line of the bed looks a little slanted in that the end on the left of the screen appears to be narrower than the end on the right. That line could lso benefit from being made a little bolder as well I think, and the side of the bed nearest the foreground should be in shadow if the window is the only light source. Likewise, given the direction of the beams of light, the end of the bed on the right should probably be lighter rather than darker, and the shadow from the curtain on the right would probably be more defined.
In terms of perspectve, the line of the back of the chest of drawers doesn't follow the one set by the top of the bed, so it looks as though either the wall is very uneven, or there is a chunk missing from the back of the drawers.
Sorry if all that seems so critical, just trying to be constructive with it though. Otherwise, I live the way you've shaded the folds in the bedding and the curtains so delicately and realistically. And I thought the lines of your character in your other recent submission were very clean and crisp. I shall have to look out for this flash submission. :)
