A very cool She-Hulk transformation video courtesy Growth Comics. (Or at least a very cool transformation of a skinny chick into a big, green amazon.)

Her legs look a little beefy but it's a nice render, still.

Here's a cute faux magazine cover featuring She-Hulk, by an artist who calls himself jquin3. The figure was rendered in Poser.
