Dream

My oars are spreading wide wings in the water
My sound of singing is gliding in the sky freely.

Music is bird dancing
Snowflakes under the sun are shining

Cold winds are shaking the windows
Sunshine is kissing the wings of flying (of "a bird"? you need a noun here instead of a verb)

The shepherd boy’s piccolo is blowing in the dreams (whose dream? what quantity? if you mean several you could just say "dreams", if you want to specify who is is "my dream(s), your dream(s), his/her dream(s) etc... )
The warm sun in the morning is wandering on your shoulder

Mixed and disorderly movement is ringing out at the street corner
The eyes looking around want to fly follow the wishes

Very good!
