I dunno. It depends on the scene.
Something like that isn't too wordy if the scene is dramatic and emotional. If the scene is tense and action-oriented, you want to keep your word choices short and punchy. Sentence structure can echo the mood of the scene.
Not must. There are almost no "musts" in writing. You can end a dramatic, emotional scene with "He wept." Short words, short sentence, lots of impact. But in general, if you're writing a fight scene, you don't want lots of purple prose with lush description and poignant word choices. If you're writing the post-death emotional trauma scene, you don't necessarily want lots of colorful, bright verbs with choppy paragraphs.
Edit: Oh, my nitpick? They wouldn't drop *into* the darkness of the pavement unless there's some kind of shadow being cast by the pavement. They'd drop *onto* the darkness of the pavement, which implies there's pavement that's not well-lit and is thus dark.
