Wow, just... wow.
Graphics - Truly amazing, your artistic abilities are very impressive. From the lizard at the beginning, to when Bitey was swinging through the trees, to the Prowlies themselves. Everything was unique, original, and very detailed
Style - This series has a very unique silent "nature" feel. At least that's the impression I got from watching.
Sound - Seeing as you gave no credit whatsoever, I'm going to assume that you did the music yourself. This is an unbelievable feat in itself. Not only are you one of (if not) the best flash artists on Newgrounds, but if you can write your own music, I don't think anything could come of your work but success. In the event that you didn't write your music, it's incredible that you found music that fits so well!
Violence - Not particularly important, although I did enjoy the fight scene with the Prowlies.
Interactivity - Um... play button?
Humor - Despite Bitey's apparent harshness, it is topped with a childlike frustration. Things don't usually work out for him, so he takes it out on others. Specific moments were the lizard, and at the very end with Bingbong.
Overall - 10/10, easily. It's clear that you put a lot of effort into this, and it really shows. Good job! I look forward to seeing even more incredible animations from you.
