Hey Pure_Morning - lookin' good - like the colors - I'm for darkening the shadows under the bed etc. a bit tho... could give the scene a slightly more real feel to it.

The lighting needs to be sourced - right now it looks like there is no roof and sunlight is shining in - GI_Joe? I'd not necessarily use GI_Joe in this case - but there may be those more experienced with it's uses that can prove me wrong here - you just need a more subtle indoor lighting if it's supposed to feel like an indoor scene.

Nice contrast between the blue tones and the red planes.
