I really like how your room has been set up. I bet those subwoofers and the bookshelves are really nice. I've always wondered about bookshelves but seem to have always been involved with floorstanding. I like the idea of effectively suspending them with lots of space underneath which probably is good for sound transfer. My room size is 22 x 15 but I do have a subwoofer along with the mains. I also have another listening room which is smaller and at times can be more comfortable but don't spend much time there
