After doing more reading I decided that the desk should probably come out of the room. Here is the new layout I am thinking of.
The panels will be the yellow things. I haven't built any of the panels yet. I have material coming for the panel behind the sofa and will put this one up first. The panels on the side walls are just a thought right now, how does this size and placement look?
I have built a little smaller one of these that will be used in the ceiling corners since I don't have too many options for traps.

Any feedback on this or adding more treatment is welcomed, Thanks.
