I can see where you are going with this. By all means play with this technique and experiment with it. But not as your actual professional presentation. I would use a fake identity (while posting work in progress samples) until you get it perfect.
If your goal is presenting a professional promotional piece for your business then I would reconsider your current sample. All the cool slithering motion effects and software techniques in the world will not make up for the fact that the content is poorly presented.
We see this with Flash based web design. The Flash effects, moving image loader graphics, splash pages, and gallery eye candy often overshadow the actual content. The content is always the King in this arena.
I would concentrate on gathering your material that shows your work: photos, drawings, before/after images and video. Gather it all. Then rank all of this in terms of presentational quality. Rank them as "excellent", "good" and "so-so." Be ruthless. Do not consider warm memories, pet projects or gimmicks. String the good stuff together as a slide show with zero effects, dissolves, music. Just let the content flow on its own. You might find that what you have is too short. This is OK: the process identifies what is excellent and what needs improvement. If you have less than stellar images of your good projects then work on producing them. This might entail producing still images or panning video or both. You might need to work with others in producing these images. This is actually a never ending process. As you add better image samples you dump weaker content from your portfolio stack.
Once you have great content that illustrates your skills then you can introduce video effects like motion logos, sound, transitions and other video eye candy. But "less is always more" as the saying goes. Let the content be the star. The goal is to attract clients. Clients are impressed by good work and great presentation that does not overshadow the work. Any little detail that is not professional in your presentation can sabotage that first vital impression.
I would study the work (webs sites, portfolios, video presentation etc) of firms that you admire. Compare the "rock stars" in your field, your competition and your own efforts. All of this will help pinpoint where you are and where you want to be. But the bottom line is that there is great danger in presenting experimental efforts that are not ready for prime time. Search engines might always link you to such efforts even when you have moved on to bigger and better things.
