Is this another 'gang' thing? I'd say they need to spend less time in front of the camera and more time behind it, but on second thoughts, they just need to be doing anything that gets their minds away from ripping off everyone else in the world of fashion photography, whether that be Terry's antics or someone's style.
In the days of proper photographers, it used to take them decades before they became caricatures of themselves and their work went stale. And given the right conditions or a fresh muse, their talent roared back into life. But M&M seem more like a used-up piece of plastic wrapping that used to be interesting to look at, but contains nothing of note any more.
