I think you did a great job with that poem, i really liked the idea of writing a poem about your little sister. Beautiful. I bet your little sister loved the poem! I can't give you anything less than 5/5, keep on writing.
"Spinning, arms opened wide
As if to embrace the sunset
A child of sunshine, of innocence"
I love love love LOVE this part! So full of beautiful imagery!
Besides that, this poem, all in all, is just amazing. So....expressive, so sincere....I absolutely love it!
