That one had some really good parts but some transitions definitely needed more work. Honestly you have some great stuff like the mask à 0:13, 1:02, the people holding hands around 1:29 but I thought the colors were too saturated, some masks were a bit rushed (can't be helped in an IC but hey, it's visible). The color consistency was good though, I liked how at the end you went from night to an orange/autumn feeling for example. I wouldn't say the same for the chara design though, same with quality of some sources.
And last but not least, the end. Even though I like this kind of amv, I know how hard it is to make it memorable. I think that a good final scene is necessary in this style and here, with a mere fade, it just feels incomplete (to me).
I actually found it pretty good, even though it didn't place so high in the end, but anyways, good job to both of you.
