I came Really Good Flash.

Begging for a 5 rating just proves one thing: that you aren't even confident enough in your own work to warrant said rating. What blows my mind is that the animation part of this was not bad at all and I loved the design of that beast, yet you decide to throw in random photos of people and silliness, which gives this a much lesser chance of being seen as credible. And I'm actually curious what the ending part was all about.
I'd love to see a complete version of just the animation part, omitting all the rest of the junk, and that result would be awesome. But this one, sadly, is not.

Really nice animation, you could make something really great with this style, and I truly mean that. However, this video is just stupid. I'd analyze it and give criticism like how I think you were trying to make something funny but in a troll-type manner by throwing in good animation and artwork, but I don't feel like getting into that, especially since it's obvious you are just trying to lure people in while repulsing/fake-scarring them at the same time.

It took you 2 years to do this...!?

It's definitely earnt it's M rating, obscene, bizzare, and unfortunatly quite repetitive nearing the end. To me I found it to be nonsensical, however art has many forms and this may be simply one I don't understand.
