and this is the analysis of '' She Walks in Beauty'' by Byron
meaning:
Of course it's obvious that this poem is somewhat of a love poem, expressing how beautiful this woman is that Lord Byron is looking at. She combines opposites (or extremes) in perfect proportions in her looks and in her personality. Whether it is a true declaration of love or a statement of admiration (of her beauty) is left to the reader, since it's known that this poem was about his cousin, Mrs. Wilmot, whom he met at a party in a mourning dress of spangled black.

mechanisms:
The poem opens with a line that doens't have punctuation (enjambment): it runs over to the next. Not only that but the next line has a different kind of meter. Poets use this mechanism together with enjabment to attract attention to certain words. For example in the fourth line, the word "meet" is emphasized. It is an important word in the poem because it is the premise of the entire poem. Opposites "meet" in this woman. Just as enjabment and a change in meter are joined as mechanisms in this poem, the unlikely pair of darkness and light meet in this woman.
Also, this poem makes use of alliteration, the repeating of the first letter of a word to get an easy-reading effect. Look at the second line: "Of cloudless climes and starry skies."

imagery:
Lord Byron describes a night (associated with darkness) with bright stars (light) and compares this woman to that night. She brings together these opposites in her beauty and creates a "tender light." Not a light like the daytime, since he describes that as gaudy (showy in a vulgar way), but a light that "heaven" doesn't even honor the daytime with.
Byron describes light and dark coming together in her appearance (or "aspect"), as in her dark hair ("tress") and the light complextion of her face. But her also says they meet in her eyes. The eyes are often associated with a person's soul, and reveal the heart. So he is suggesting that opposites meet in her soul as well.
Note also, that Byron says that if this darkness and lightness wouldn't be in the right proportions ("One shade the more, one ray the less"), her beauty wouldn't be completly ruined as you might expect. He says that she would only be "half impaired," and thus still half magnificent.
