Very well thought out storyline. I like it! You're also one of the few people who seem to write in rhyme scheme. Great job at that!
Critically though, the rhymes could have been a bit better and concise. Your paragraphs are too short with only two lines. Grouping them at four lines each would have given you more variety with the rhymes.
They syllable meter could also use some attention. Different paragraphs use different syllable schemes. Keeping uniformity would give the poem added beauty.
Well written poem, very cogent story line. Keep it up!
