Grey yun color ng ceiling, compare mo yun white ng cornice sa ceiling. Walang acoustic treatment yun walls pero may suggestion si ashley of audible illusions mga acoustic panels, although ok naman yun sound pero anything that would improve & minimize reflections is welcome. Just finish this theater, now thinking of improving it na, gastos nanaman. 
Hehe. Tama ka nga naman.
Enjoy ka muna ng bago theater mo.
Now having said that ... malaki talaga bagay to do some acoustic treatment on floors and walls. Kahit long-term project, dapat pag-isipan na yun.
I am still concerned about the color of the ceiling. Even if it's gray, it looks like a very light gray. I think it will cause light reflections and the perceived contrast ratio will decrease. Pero tingnan mo na lang. Anyway, that's just a paint job. Mas mahirap ang acoustic treatments.
I really like the color scheme, pero I hope di madali madumihan ang white baseboard mo!
Cheers and enjoy!
