IMO the atmosphere was intense and dramatic (think it was due to the echo effect on the voice and the solo violin with streched out notes), the voice was clear in diction and emphatic in tone, adequate volume (pending more to the loud but without reaching a scream), all of which I think help well to make an annoucement sort of thing for the event, if that was the goal (I interpret so).
The drum beats during the name listing I believe worked well for showcasing a noticeable rhythm that one could tie to the rhythm of many kinds of poetry.
The last part with the lines that felt very fluent, genuine and improv-like to me also I believe falls perfectly in line with the idea of the event, even if improv on it is not necessary for participants (though we did see some of that then, heh). I also think the short, rhymed verses at the end helped with fluidity (and also to make us think of poetry).
I'm docking points for I felt the name listing was a bit repetitive with the beats (even though I still commend the rhythm like I said), I think I captured slight differences in intonation through the names' pronunciations so I don't see why not the idea of on-point notes from different instruments or something else just for variety.
And speaking of variety, I believe a higher degree of it for the melody, different sections, changes in the pace/speed/rhythm/idk or something like that would also be nice, maybe around 1:05 at least? Even for an announcement.
My opinion here. Still, rock solid stuff, awesome work!
