outstanding flaws?

Hi all. I wanted to post some pics of 2 rooms i now have for your enjoyment and your 2 cents on any outstanding flaws you see or red flags I should know about. The only design advice I got on this project was pretty much from this site. I am using this studio as a living space as well... Details: in an industrial area in Brooklyn, NY. We don't have to worry too much about the neighbors. We are on the 2nd floor of an old creamery from the late 1900's, sitting on a slab of concrete at least 6 inches thick with some old-ass brick on top. There are two pictures: one room has a gray floor and one has a green floor. (Not in real life!) floors: in the gray room, the floor is red-brick. The green room has carpet on top of some nasty epoxy coating over the brick. walls: in the pictures, the mustard-colored walls are double walls, made of lumber, with double-layered sheetrock on the outside with green glue in-between. They are stuffed with insulation. Any other walls (the outside walls) are glazed brick. Windows exist only in the gray room, and are marked in blue. Ceilings: 12 feet tall Other: the gray room is a symmetrical trapezoid with a 4 degree deviation-from-90 at all angles (two corners are 94 degrees, two are 86 degrees). I planned on mixing at the small end, with my bed at the big end. There is a (movable) free standing closet 8 feet tall, 3 feet wide in the center of the wall at the big end of the room. the green room's walls are 90 degrees perpendicular only at one corner, the rest deviate between 6 and 9 degrees, to keep the room from being a pure rectangle. The green room will be the primary live room, and will have clouds that we can raise and lower depending on how we want the room to sound. There is no glass between any of the rooms; visual communication is via isight cameras. we are mixing/recording multimedia stuff for TV/movies and also acoustic music. Our budget is tight, by now. I have a couple thousand to play with, but most of that is going to good gear. I think that's all there is to say. My questions: 1. Any outstanding bad things going on here? If so, can they be fixed? 2.What treatment would the gray room need in order to make it acceptable to mix in? 3. What would be a good 2.1 speaker placement in the gray room? This is a lot to ask, and I know no one's getting paid to do this, so any help is greatly appreciated. We (us builders of this project) are 2 musicians who have a little experience, a little intuition, and lots of grit. I can tell you this, no matter how bad the rooms may be acoustically, they have great separation. One of my roommates practices Chopin in the next room, and I can hardly hear her. Thanks again to any and all help!
