Excellent production, my friend!
This being newgrounds, I'm sure you know it's users are accustomed to a certain set of familiarities, such as file size (as you have already mentioned), format, and subject matter.
Without getting into the details and politics, you have managed to break through all those barriers and presented newgrounds with something unique, and downright awesome!
There are a few technical aspects that could use some "ironing out". For instance the animation could be improved upon a bit, but that's more the animator in me talking, not the film maker. And that's what this was. It's a blend of different medias, and honestly, the jerky animation worked well with the childlike dream aesthetic. It's New Media, and well done!
Keep it up and I look forward to seeing more of your work.
