Answer:
Line six should be the start of the second stanza. It would fit better there.
Line nine is sweet, I would change inches to meters. "And if beauty were meters, he'd go on for miles," sounds a bit better.
Line fourteen should not have the word headed be in past tense, instead change it to heading.
Line eighteen and nineteen reads;
We all have our flaws, but when I view you through my eyes,
perfection is all I see.
I would edit it to say
We all have our flaws, but I can guarantee
that when you are around, perfection is all I see.
There are small details I would changes in the forth stanza. This is only to make the words flow better when reading.
"Where your treasure is, your heart will be also" is how the saying goes.
We are not promised tomorrow, this everyone knows
I know I don't need to prove my feelings to know they're true
because my past can't compare to the experiences I've shared with you.
There are a few places throughout the poem that do not rhyme, but still sound alright. I'm not sure if the intentions were to spill your heart out with honesty and rhythm, or something else. Either way, you did great! Overall, I personally wouldn't change anything else. It is heartfelt and loving, as well as being reassuring and comforting in a way.
You did amazing! I hope you have a lovely day/night!
