I agree with all of Ellis's suggestions, and I think the cover is nicely done, but I would be in favor of a fuller, more dynamic compostition. The shapes on the page don't really activate the space; it's very static. The small female figures make the composition kind of "spotty" and broken up. It would be more interesting to see them interact with the main figure.
I googled the reference picture of Bond that the artist used and found some other Bond posters from that era. I'd like to see something more like this poster used as a basis for the parody. The central figure could still be holding the gun; he could even be wearing his tuxedo in the tub.
Hope I'm not suggesting too radical a change for the artist. It means starting over from scratch, (sorry, to whoever the artist is). What do you think?
The picture I just added (second one down) is an example of retaining the "collage" effect but with the background and compositional shapes used well. I like the slightly stylized cut of Bond's jacket that gives the shape "oomph" and definition. Look and the nice negative space around the figure as it relates to the border. And that negative space is filled with dynamic shapes as well.
