When composing a piece of artwork, we generally work with three elements: the frame, the positive space, and the negative space (also called white space). The frame is the bounding size of the artwork, the positive space is the subject, and the negative space is the empty space around the subject.
The river is deep,
it touches my life ....
like the waves on the sand

Time stands still as I gaze In her waters
She eases me down, touching me gently

Take me back to my boat on the river
And.. I will never come back again

Lyrics: STYX - Boat On the River
