What's behind your chair? Diffusion works best on the back wall behind your chair. I see you have some GIK 244 panels. How did you arrive at those positions? Did you experiment with a lot of different positions or just pick the spots that seemed right?
I've been using a combination of 242,244, monster panels, and Acoustical Solution diffusers. I've done a lot of moving panels around the last six months to reach a balance that I feel is right. I think you need to try many different panel placement options.
From your photos, I would start with one of the 244 panels centered on the frt wall behind the speakers, move the other 244 panel to the back wall. It also looks like you have a 244 panel on the ceiling between the speakers. I tried a 242 panel hung like a cloud and it lasted only a week before I removed it due to a reduction in acoustic space. Maybe remove the ceiling panel and try a thinner panel there or a diffusor.
