Alright, i'll be as harsh as possible, everything in this picture is completely horrible, never use FPSC again, you're a disgrace. Haha okay i am joking, obviously. The room overall looks actually pretty good for a new FPSC user. With a good use of lights and nice entity placement (as in the room doesn't appear crouded but isn't bare) you've done an excellent job in those departments. I must say the bed doesn't exactly fit the scene, the look of a more modern and/or even futuristic one might flow nicer with everything else.
In a nut shell, i must say you have a pretty much fantastic start here, but definately upload more pictures, i would like to see where you go from here. Remember, if you ever need any advice beyond what you you can get from this or any other thread, simply searching around the forum for advice is the best. I know people like 'Nickydude' have made and/or compiled some superb tutorials and support threads showcasing very detailed, very helpful tips on level design, and overall FPS game making.
The best of luck to you, cheers - Braden
