Trapped in the Serpents Garden

In captivity he holds his flower,
She sits on the window sill upon the high stone tower.
Flowered vines stretch around,
Its green leaves obsession bound.
Metal bars, reinforced concrete,
Still she looks on through the gaps, feeling incomplete.
Her beauty everlasting an ageless grace,
Not a wrinkle, nor a blemish, on her porcelain face.
But slowly her heart starts to harden,
Forever more, trapped in the Serpents Garden

Dream I had, wanted to remember it, so I wrote it down in a poem. Review if it sounds O.K
