Mix room acoustics for odd room shape

I've posted pics below rotating clockwise from where I want to put my gear. Thanks all.

Could you do an accurate diagram of the room in SketchUp or something like that, and post it here? It's hard to get a perception of the dimensions, shape and geometry from just photos.
