Fellow speaker,
When developing your speech delivery, work on the big things and then, after you are doing those well, focus in on the finer points. First work on the vocal variety (e.g., loud, soft, harsh, etc.). Next plan out and practice your emotional delivery so your emotions "come alive" for your audience. Finally experiment with the pacing of the speech (e.g., where to go faster, slower, etc.).
Delivering,
Tim
