Just a few suggestions for your reference. They might not be correct :)
With the gentle breeze, (under) the white clouds, （or "With the gentle breeze and the white clouds". You need to have a word to connect breeze and clouds, otherwise, it doesn't make sense)
In the spring the seed eventually sprouts
Going through the darkest time,
Flying with all of (the) petals in the prime (or “Flying with all petals in the prime")
Like butterflies flattering (flutter) the wings (in the next verse, you use "sing", not "singing", so maybe you should use "flutter" here to keep consistent)
