On the busy I would suggest trying the animation with just the 1st and last images...
the eye fills in the rest and it would make your animation more realistic. A more visible color would also be nice on the busy.
Cingular cell phone company logo: I would remove the dot to make it more original and just vaguely referring to the co. logo.. as I am not sure a simple disclaimer would cover usage of their logo. I do agree that it is copyright infringement to use it as it presently is. (thanks sixλxis)
Help is not a great image and I would drop it for a remix of the cell phone or working images.
knock-knock.. are you there?
