To Whom My Heart Belongs To

I want to improve my writing, so I would like if you would comment. Thank you.

To whom my heart belongs to

Your smile brightens my world
When my world has darken

Your voice is a song
And I just can't stop singing

Your love for me is a life jacket
When I'm stuck in a life-threatening storm

You are my heart
Giving life through my veins

You are my everything
