Hello,
If this is the Alt. #3 program and vignette, my understanding is that this is probably the toughest combination of practice program and layout.
1. I think in 'JO' the clearance between the back edge of the chair at the exec. desk and the adjacent credenza encroach.. I'm not entirely sure but although you have 3'-0" clear behind the desk and book case, as well as the credenza, my understanding is that the circle needs to be able to be 'traced'. You may be fine - I really can't tell at the pinch point.
2. According to
http://arehelp.webs.com/sd, the posture chairs and worktables should be treated as separate furniture - have you seen evidence to suggest otherwise? This is how I've been treating everything but it makes sense that you'd be able to put a chair infront of the worktables, similiar to how the coffee tables and lounge chairs work. Just taking the program literally that may not be the case.
3. Biggest error I see at a glance, is in SO. You have a lateral file(?) facing the back of the door that swings between JO and SO. Seems like you might've meant to rotate that to face the other direction ... I think it can face other CFA, but not the actual back of the door.
