Room Analysis Before and After...Please Comment

Hello all, Below are my room dimensions and a before/after of the room with no sound (baselines), and pink noise through the speakers (via cd player). All of this was done with the AKG C3000 mic in the mix "sweet spot". The audio was recorded in SoundForge via a Digi001 interface. The resulting waves were analyzed in, and graphs taken from, HarBal. The bright green waveform is the After, this darker green (olive-ish) is the Before. I plan to build some more absorbers and place them on the side walls, but I wanted to get opinions on this room. NOTE: When I mix I place "acoustic" blankets over the window and doors. They were in place when the measurements were made. Thanks, Chris
