Check this out. I had to get a screen shot so you could all see Galactus's Head for yourselves.

I found it at approximately 1:19:51 into the movie. I also included a cartoon picture to compare the head shape to.
I hope this clears up any confusion people might have about where the cloud takes shape issue.
Anyways I thought to movie was a great adaptation and I have read the comics. I think that the comic story would have been a bit better to portray in the movie, besides it would have only changed a little bit and possibly extended the movie by a fraction of time if any at all, plus they could have developed another movie just too the Silver Surfer.
