Not bad, though you'd do better with thicker absorption on the front and rear walls, and real diffusers where you show those plastic thingies. I wouldn't worry about the room being too dead. It's too narrow to get a "good" sounding ambience.

It's funny you should mention that, because now that all the new walls are up and with the room completely empty, the ambiance is actually amazing! It doesn't sound like it has a low ceiling and there is no audible flutter echo somehow, no matter where I go in the room and clap/snap/shout. Although the reverb time is ridiculous! haha. Audibly it's about 1.5 seconds long. There IS a modal ringing though (which should be fixed with my treatment plans hopefully). I forget which note it was. I just sung through a scale until i found the note that really rung. But that's to be expected. Just thought I'd mention that the ambiance actually sounds pleasing with the room empty and barewalls/ceiling/floor.
I altered my plan slightly. I now am now doing superchunks, putting thicker absorption on front and back walls and putting more hung panels on the ceiling instead of using as many foam squares on ceiling as in the original diagram.
So now to all those that were kind/generous enough to answer my original post, my questions are as follows...
See the attached new diagram below (I have left out a floor standing cubby that will be along one of the long walls for storage and also left out the combo amps since I figured they were negligible for this). I had ended up making a few extra mini panels out of left over materials and I also have a bunch of those foam corner "bass traps" as well as about 100 foam wedges that are not in the diagram. Not to say that I NEED to use all that extra stuff, but I should probably use up at least the extra 4" panels i made and the foam "bass traps". i list what i have left over in the diagram and any of it can go either on walls/ceiling where there may still be reflections, or straddling corners where wall meets ceiling in various places, especially above the mix position.
That ACTUAL questions:
1) where would you put this left over stuff? I'd hope to use it for more "bass trapping" or whatever these leftovers can provide as far as bass trapping.
2) should i fill in all/most of the empty ceiling space with those cheap foam wedges for what it's worth or is this enough? Floor will be reflective and the ceiling is 7' so I believe my questions to be valid enough.
3) Do you think those monitors placed the furthest to the outside of the mix position will "block" the superchunks from working effectively? They are JBL J2080 consumer hifi speakers for a "hyped up" refernce and to be used as "midfields" for kicks. They will be on stands and are approx 22" tall X 11" wide X 10" deep.
