"But why the furries ?"
That is what you must often read concerning this piece of work. I don't know wether you're into this so-called furries fad, and even if you were, I wouldn't judge you or your work depending on this factor, but I know one thing, the design of the characters if very much flawed. For one thing, adding ears, or making an anthropomorphic cat out of nowhere is really what taints this movie for me. And it may very well cause people to disregard this film. That's one thing. The other, as some already noted, is the relative dullness of the environment, everything is way too clean and polished to look real, though I must admit you've got impressing modeling skills, and an eye for urban environment.
Parallel to that is the colour scheme, which is very basic and gives a rough-feel to the world, as if you hadn't finished it yet. As for the story, well, it's too cliché and mellow for my taste. But again, I don't think you're into brutal, mindfucking or sheerly bizarre scenarii. However, in the end, that such a promising 3D animator is on Newgrounds is note-worthy at the very least.
