Hi Dan!
Imo it mostly looks good. I commend you on mounting the tops right to the ceiling. I guess if I were to offer anything it would be to move the couch forward off the back wall
If you can. Theat will help smooth bass out and give nicer separation from your ears and rear tops and surrounds, instead of being all in the same kind of area. I couldn’t fin the CC speaker so wherever that is, I’d excavate it and put it directly below the screen. To me the subs would the first equipment to upgrade but budgets can be tough. I get that. Dynamic volume, Ime is useless. It basically just levels the volume. So dynamic swings are lessened, like commercials being louder or someone sleeping in another room. DynamicEq can be useful though. But do know that along with raising bass and treble, it also raises the volume level of surround and rear top speakers.
