Oo.. and a couple of things if i'm allowed to crit a lil.
- a hanging big piece of cloth in some nice color covering the ceiling lights would be quite pretty

- the big separation between each of those wooden floor tile block thingy's is too big, can you make it narrower ?
- plants brings rooms to life

- lightfixtures above the artwork would have a good effect on it too
- maybe not too many windows in the room as you were planning, that could look weird, use the light you have more effeciently instead and let it lit your room and cover the big empty wall to the left with something else instead.
- i agree about the blueish wall
- curtains is a good idea too
