I would definately suggest
Spending a little more time practicing your tweening of malleable blobs such as this one before attempting anything similar - it's definitely passable at the moment but you need to work on making it seem like the form of the shape is actually reacting to the movements in realistic or pseudo-realistic ways.
Another little thing I would suggest it that some of your shots are framed in a far too static manner. add a little dynamic camera panning or lighting just to make the shot feel more natural or lively.
