I am LOVING your use of metaphors- especially in the first three stanzas. The comparison of yourself to a puzzle, painting and tree are wonderfully done- both emotionally and visually stimulating.
If I have any constructive criticism it would be regarding the use of the word ‘life’ three times in the 3rd and 4th stanza. It felt a little forced to me. I found myself wishing you had opened up your vocabulary a bit and used something a tad more creative.
Otherwise, this poem is solid- a great read- one that I very much enjoyed! I hope this is helpful. Thank you and have a happy new year!
