I would clean up the lower flash. What I mean by this is that i would remove the background that the movie is fading in and out from, it shows the line and the line doesnt need to be there. it would look cleaner.
Also, I wouldnt add a banner to the front page as you have a clean look and by adding the banner it will muddy up the clean look that youhave going.
I too would suggest a logo redesign. Something that is dynamic, yet easy brandable across multiple platforms and formats.
If you need help with that, PM or email me. Email would be faster response.
