First of all, basses. What an awesome sound. What an improvement. It's like you left as boys last rehearsal and came back as men today. Bravo!
I liked the way your songs sounded. The balance definitely improved.
I think you should practice "Bridge Over Troubled Water." The ending soprano part needs some serious help. If you have the high Bb, let me know. Don't try to be a super hero and hit notes you don't have because it only drags the sound down.
Anyway, keep having rehearsals LIKE THIS.
Do not forget to bring your folders back for both sectionals and rehearsal. I think you having ownership over your folders is an essential skill that will bring you the the next level of responsibility and awesome.
