I\'m finding that the whole piece is weighing heavily to the left here. The first and second vios sound like they are probably in the right space but it also sounds like your violas are sandwiched in there with them. Try bringing them more center. I also am not detecting any cello working at all (unless it\'s in the higher registers and blending with the violas) which is what is making the whole right side empty to me. That pitzy c-bass sounds so alone alone over there at the moment. If you do have cellos working they could pretty much be where the c-bass is and then slide said pitzes a tad more right to fill out your stage.
The reverb sounds good to me tho. The best attempt I\'ve heard this week
You\'ve been a busy boy! Keep it up.
