A waste
This frustrated me because there was potential to do something really sweet and original, but it just fizzled out into nothing. There was no story!! And that is where most Newgrounds cartoons suffer - they don't bother to write a captivating story.
The drawing is simple but the way you've animated it is lovely. The spinning 360-degree shots are fantastic. I loved the long shot of the field as everybody congregates around the stereo, tracking back slowly to see these giant whistles and beach balls. It's a wonderful and original image.
The two 'romantic' leads don't do anything though - they smile at each other (that wasn't animated particularly originally however) and nothing comes of it. The goofy dancing was funny, but the whole thing seemed pointless.
I also hated the song, but I guess that's a more subjective criticism.
There are a lot of positives to take from this, but overall I see it as a wasted opportunity to do something really great.
