The elements in poetry

the elements of poetry are form, voice, sound, imagery. the new colossus had stanzas. It was arranged neatly into short rows of sentences. It isn't split into verses. The poem wasn't read aloud by the writer. i dont think that the new colossus had a rhythm but the words rhymed.
The first sentence of the poem was " Not like the brazen giant of greek fame.", i thought that this part might be simile. It might be simile because it uses the like or as to compare the statue of liberty to the greek god Helios. The rest of the poem would be metaphor. Metaphors are also comparison without using like or as.
