Who's the Herald? I mean, Galactus traditionally has a herald that surveys potential snack items (i.e. planets), e.g. Silver Surfer, Terrax. Also did you know that Galactus is kin as a cosmic entity to the Marvel universe's personification of Death? Anyway, you've certainly chosen an interesting character to explore for your animated film with an incredibly rich backstory and fascinating cast of characters. Definitely one of my favorite Marvel Mythos characters. Judging from your stills (which are impressive) you're doing a good job of capturing the aesthetic. It would be awesome if you somehow squeezed an appearance by Thanos in there! (or hell, any of that Jim Starlin stuff).

Caveat... you're apt to inspire the wrath of comics uber-geeks if you make a wrong turn with this beloved character. Looking forward to seeing its completion.
