Take more time.
Seriously, 6 hours feels like a long time, but it takes at the very least 2 days to pull off something passable by Newgrounds standards. You need to put effort into your flash, this stuff looks like it was drawn in 5 minutes, and then animated in 2.
It takes me atleast 3 tries to get my pics to look right, and you gotta know that to tween an entire flash, you gotta get the tweening to look really smooth. (Watch "A Wizard Creates")
Sorry, but this'll be lucky if it passes. Better luck next time.
