Personally, I prefer your old room to the new design, but admit that there is a "wow" factor in a themed room (especially showing it to someone with the lights on) that can be appealing. In that context, I think the room looks cool and I'll be following the build. I'm just sad to see that you are dropping the DYISG speakers.
