Irodorimidori accomplishes satisfyingly enough within its 8 episodes of 3 minutes: It has simple backstories so the events don't really seem spontaneous; it has occasional flares of individualism that show off the obviously pre-natal personalities of our music aficionadas.
For its time frame, Idorimidori is able to deliver something seemingly competent to the audience. However, this in itself, in my opinion, is what prevents it from being any greater. It branches out some, yet many of these branches are forcibly torn off by its short duration and the ability to elaborate on them.
There is no action after their performance asides from a brief backstage exchange. There was no transition in between Episode 7 and 8; they went from being backstage straight into the performance upon the first seconds of Episode 8. The main purpose of their performance itself was lost, as their school never stated who won nor did the show even display what happened after they got the reward.
It might be asking almost too much from a show shorter than most single episodes of anime, but filling in gaps such as the aforementioned would make it a better show overall.
Asides from that, the actually music itself wasn't all too bad, I liked it. It was a moderately enjoyable, shorter watch.
