While the style is very fine here, very much to my liking, and the animation is smooth, I'm afraid I don't think it really fits in the Movie Portal. It's got no sound and is very short, and, like you say, a test. The Movie Portal is, in my opinion, more for finished animations, like self-contained projects that have a sense of completion to them that makes them like a "Movie". However, the Art Portal accepts GIFs and I think you could post this there and it would fit rather well. I guess we'll see how the users vote this out, but that's my recommendation.
