"All alone" at the very beginning alliterates, and because there's only one initial sound, there's an illustration of that singularity.
In the line "With the eyes and the lips and the skin that I know so well," "and" and "the" are unnecessarily repeated, and this helps to give a sense of degree (for "so well"). Polysyndeton is the rhetorical term for the repetition of conjunctions; I don't know if there's a term for the repetition of articles.
