Welcome! And being hesitant never helped ANYBODY.
It's a solid mix.
If you handed it to me, I'd send the Left Guitar to an Aux track, with a quick delay (100% wet), and pan it to the matching right side of the track, so it's wider. maybe only half as far right as the main track is left... Then lower the volume so that it matches what's there now, since the volume is perfect.
Then centre the bass, it's angling the track to the lower-right.
But everything else in the project is perfect! Nice work.
