Very nice scene! :yes:
But perhaps the pattern would be a bit intense for me, right after waking up. 
Yea 
and thanks
That looks really good ! The only thing that is weird, in my opinion, is the table material. If you look at the edges of the table it looks quite unrealistic, because with this kind of wood, you usually have some displacement going with it.
Maybe it could be better with a little bit more of defocus or with a different wood ? (Though I have to admit, the wood texture itself fits perfectly with the colors of the image !)
Good job ! 
you are right mostly i should have used displacement map it would be better thanks for the tip
