Copying someone’s entire style saves you time and costs you your own voice.

Imitation is a legitimate and necessary stage, and almost everyone learns a craft by copying someone good. It turns into a problem when it stops being a stage, because a complete copy leaves no room for whatever only you would have done. You reach competence faster and then stall there, sounding like a slightly worse version of another person. Time saved gets paid back in sameness.

Borrow the technique and refuse the mannerisms. Ask what you would do if you had never seen their work, then do one of those things.
