The more you will add as imagery, the more you will kill these... Mostly when they are so rich and different in colour the same time.
PS: it is possible I have not understood your sentence. But the arts are for the front anyway. I never understood why you seem all willing to avoid the film credits on the front. If film posters would figure exactly as they were made at the moment of the releases for theater on DVD covers I would personnaly don't see what to change.
