Looking for some advice on studio make-over

Hi Everyone, I'm new to this forum and I've familiarizing myself with the rules before posting, so I hope this post will be okay. I'm attaching a file from Google Sketch-up that I made of my studio space, and having never done this before I have no idea whether (or how) it will be viewable. If not, I'd welcome some advice. I've marked the dimensions of my space on the drawings. This is a wooden outbuilding that is raised on pilings. All of the interior walls and ceiling are wooden and the floor is 3/4" plywood covered with some very, very thin industrial carpet. Noise is not an issue. I'm in the middle of the woods, so I don't need any sort of sound isolation in either direction. This space needs to double as a control room and recording space. My current resources are: 10 2x4 panels that I made from Owens Corning 705 Fiberglass (I think it was 705? Two inches thick with no reflective material on it). I covered these in muslin and framed them. 6 diffusor panels from Microcosm Media (the 624 panels) http://www.microcosmmedia.com/ I'm a woodworker, so I have the tools and materials to build just about anything I need to enhance the acoustics. Basically, I'm wanting to make this into a nice space for recording and mixing. I mostly record vocals, acoustic guitar and flute. So far the sound is okay, but definitely is not great. I'm hoping for some input on where to place everything and possible modifications I might apply. Any suggestions would be most welcome. Thanks!

I forgot to add a couple of details: There is a closet/machine room shown on the plans (roughly 4'x4'). There are also two windows shown (2'x3' and 4'x6'). I have a set of Dynaudio BM5A near-field monitors that are on stands. Thanks!

Aloha, Perhaps something like this? - side walls @ 6 degrees each (right unit movable for access?) - rear corner traps - speakers @ 30 degrees each/60 degrees total Aloha 8)
