Bedroom with cycles

Working with this Interior shot, need help and suggestions.

what kind of look or feel are you going for? It seems a bit dark.

actually looks fairly real to me, lighting-wise (a hotel room with the lights off) but the bed materials and sheets need a lot of work to look right.

Yep, I want it to look like lights is coming from the direction of camera through a window, should I do additional lighting? Or I should just crack up the power of same light? Yes, I\m working on materials now, this is just basic look i want from them.
