I'm probably one of the few who can say "yeah this is my bedroom"
Actually, you are the ONLY person that can say that - it being YOUR bedroom and all.
I don't think your room looks to small. While my living opens up into a much large space, the room itself is only about 18 X 12. I find that I've got plenty of space to let the goodies breathe. (Though there still is a tendancy to turn it up a little too loud - because it appears to sound better that way - which creates some conflict with the wife).
The ceiling does look great, too, by the way. Good job!
