Yes, I agree, it is definitely a metaphor- it’s a thing regarded as representative or symbolic of something else. Onomatopoeia is the process of creating a word that phonetically imitates, resembles or suggests the sound that it describes. A simile is a figure of speech that directly compares two things, often using the words ‘like’ or ‘as’. And personification is the attribution of personal nature or human characteristics to something non-human, or the representation of an abstract quality in human form. Hope this helps!
