There are several grounds they may reject it on - it looks like there are gradients in the comic figure, but you've not shown any halftones to indicate this. Also, the comic figure, itself, is taken directly from the cover of the American versions of the Hitchhiker's Guide books, and is likely under copyright (especially, since you can't really argue the use of the figure, itself, is parody).
Woot has gotten much more strict in making sure that they don't violate any intellectual property rules, and I would guess grahamcrac is making his/her predication based upon this.
