Sound effects...
You obviously put a lot of effort in making this look good and it certainly does : )
I agree you can very well see where the resemblance to Adam Phillips' work, although he gets absolutely ever detail right. Your flash looked slightly more... - "scribbly" for lack of a better word. The drawings just weren't as smooth, but that's probably intended. But it doesn't matter, it looked great in its own way.
If one thing bothered me, then it would be the sound effects. There were a few obvious looping sounds in there that got somewhat annoying, and the sounds weren't always just right to fit with the animation.
That's just some of the good and bad, constructive criticism, you know ;)
But I did like it. This is among the best stuff on NG.
Keep it up :)
