Amazing.
The animation was a huge improvement from your other cartoons. There was a lot of frame-by-frame animation and all of it is really smooth and nice to look at, especially since it's all done on ones. Though the animation was great overall, there are a few minor things I'd like to go over.
I think the rain animation in the first shot could've been improved, maybe it'd be better if you drew the rain once and then panned it down for an endless loop. I also think that the way it just sort of fades out before the next shot is a bit weird, I think it'd look better if it just kept raining.
Really smart use of music choice. The music set the atmosphere for this scene and it really enhances the emotion the viewer could feel through this scene.
The voice acting was really good, everyone who voice acted really nailed the emotion of this scene. There's a minor issue I noticed with the lines, though it's not with the voice acting itself, it's about the sound levels. Frogman's lines are noticeably louder than Pico's, and sometimes the background music makes Pico's voice seem a bit soft, but it's okay for the most part. For Pico's "wallowing in my sorrows" line, the reading seemed a bit too fast, unless that's what you were aiming for.
I really like the writing, a lot of emotion in it and I agree with the message about NG's popularity declining.
Overall this was really good and I look forward to seeing more!
