Awesome is the word. You have successfully crammed a full-blown home theater into a dorm room. Very nice.
The lighting is very slick. At first it looked like the back wall was floating with a gap between it and the side walls/ceiling, but now I see that is just a trick of the light.
Only criticism would be that it appears you actually have a mirror at the first reflection point (where the sound from the main speaker bounces off the wall and hits your ears). Normally the mirror is only used to determine the reflection points then is replaced with absorbent material to improve imaging
