As a creative destroyer, I have spent years honing my craft of tearing down the work of others and replacing it with my own mediocre attempts.
My methods are simple: I start with a solid understanding of the original work, then proceed to shred it apart with reckless abandon, replacing it with something that's almost, kind of, sort of similar.
It's a delicate art, really. One must have a keen sense of what works and what doesn't, and be prepared to defend one's actions against the onslaught of hate mail and angry comments.
