Okay before I get, the last bit made me crack up a bit more than I was hoping for.
Anyways-
I remember saying something about the 'qualities' of your last flash, Event Horizon. Comparing this flash to that, you've improved. Even the dance was well synced, which I'm sure was the hardest part. Half of me wanted to say maybe you've overused ...birds, but the more I watch it, I feel like they belong.
As always, the song choice is amazing, and you do well to animate to it- emphasis and all. HOWEVER I know the story to the flash- not really anyone else does. So this flash does almost nothing to explain whats going on. I recommend a prequel. Now I would say type the whole story in the description, but not everyone reads that- so you have to make sure your flash will make sense.
Although that's a bigger flaw- I really see no others in this flash. I say this every time, but I mean it: Keep it up <3
Music: 5/5
Sync: 5/5
Detail: 4/5
Quality: 5/5
Effort: 5/5
Story: 3/5 (Now like I said- I KNOW the story, but if you never told me I would of just liked the flash without knowing what was going on.)
Overall: 4.5/5
