I think it's great that you are experimenting with new animating styles and techniques. I think that really helps animators learn. I also give you alot of credit for making your own music. That gives you alot of credibility. I thought the graphic was great, very well drawn. Music was great, quality was good, and it helped set the mood.
However I wish it wasn't just a shape tween. I didn't really feel the emotion I think you were trying to capture. I think it would have helped your case if there was a story behind it, maybe some narration even. I think a story can really make or break an animation, and this animation was lacking in it. If you wish to submit experiments, I think they should go under "Dumping Grounds" (http://www.newgrounds.com/dump) and I think it should be left out of the portal.
Didn't mean to come off as mean or rude. That wasn't my intention. Don't give up, you certainly have the skills to become a great animator.
