Judging from the pics, your room acoustics are most likely on the lively side because of the large bare surfaces that abound.
Highest priority should be to add absorption along the right side wall (as seen from chair). Unfortunately, the right speaker is closer to the wall than the left, so treating this wall is especially important.
Next add absorption to the wall behind the chair, then diffusion panels behind the loudspeakers (many prefer the opposite arrangement...depends).
If you are feeling adventurous, add a bit if absorption or diffusion to the ceiling (hint - have someone hold a 12"X12" mirror square flat on the ceiling while you sit in the hot-spot. keep repositioning the mirror until the tweeters can be seen. That is where you put the treatment. Use this technique for the side wall, as well).
Have fun and good listening!
