Need opinions on ceiling reflections


All,I have a soffit that is running length-wise on the LEFT side of the ceiling (picture in my system). The ceiling is 8' and the soffit part drops down about 1'. The speakers and sound panels are positioned with a precision of 1/8th of an inch and it sounds amazing - especially on the RIGHT side. The music appears to come from way back and way outside the RIGHT speaker and you can actually "look" that images of various instruments playing in those empty spaces. But I have a heard time "seeing" those images on the LEFT side speaker. I have a feeling that this issue happens because the reflection point on the left side ceiling is a foot lower than the one on the right side ceiling. I was planning of getting some acoustic foam and attach it to the ceiling using T-pins (since it is a textured ceiling and foam tapes will not work). I assumed that this will absorb the reflections and could work on restoring the proper timing/clarity on left side.

Could you guys weigh in and let me know your thoughts? Please feel free to let me know if I am off and the issue is completely different.

@bigby Thanks. I did take a look at you room. You have amazing room treatments and that room looks pretty nice and big. Those ceiling treatments probably do wonders. But I am looking at something simpler. I also use GIK throughout my room. But I don't think they would sell a single panel. Nevertheless, let me reach out to them with my requirements.
Fiberglass is a nuisance. It has to be covered correctly or glass fibers get into the air and some of us, like me, get itchy just looking at the stuff. Acoustic foam is every bit as effective down to 250 Hz  and eons easier to use and in the end cheaper. It is also easier to specify  for a certain situation in terms of thickness and profile. 
Now unless you are lucky and able to have a room in  your house that does not have parallel walls the single best way to deal with parallel walls floors and ceilings is to have speakers that do not send sound in their direction. Then if you are really clever you make your room without a rear wall and you don't have to worry about that either. You can leave your side walls and ceiling live for ambience and if you have speakers like mine or any other dipole just a little absorption behind the speaker using foam or fiberglass, if it does not make you itch completes the picture. 
@mijostyn Everyone needs to define what's too much hassle. My wife made the case for the pillow in 30 minutes, the fabric is nice, and there's no mess at all. And they work wonderfully. Still, everyone needs to figure out what they're capable of.
The only thing i can say is that you may have a hearing loss on your left side due to driving a car with the window rolled down it is a common problem and you will notice that a lot of recordings and mixes are left channel heavy because of it.
Very good point indeed. But I don't drive with window rolled down. The vocals are dead center. The songs don't appear left heavy. I think there is some smearing going on on the left side. The images appear pretty close to the left speaker. I want them coming off at least 2 feet to the left and 4-5 feet behind the left speaker, just like how the right speaker images. The images in the middle appear close to the wall behind which is almost 6 feet away.
