In my recordings you can hear a lot of nasty room, sound bouncing around and the room has a real boom to it. Trying to tame it.
Comes out to about 150 sq feet of treatment. That is about 30% of walls.
I would definitely suggest making all of those panels at LEAST 4" thick. Note also that an airgap behind the panels on the walls may effectively increase your panels absorption, especially for bass notes, depending on the material you're using. Location of the panels looks great, but you never know until you test it!
