Imaginary Garden with Real Toads offers a mini-challenge, to use the Waltz Wave Form in response to the prompt.
The Waltz Wave Form requires 38 syllables over 19 lines, in the following configuration:-
1,2,1,2,3,2,1,2,3,4,3,2,1,2,3,2,1,2,1
Below is the picture prompt (by one of my favourite painters) followed by my attempt

'The Singing Butler' by Jack Vettriano
Dance
With me,
Sway
With me –
Let us whirl
And twirl,
Two
As one
Together
‘Til music ends
Forever.
We’ll dream,
Sigh
Softly,
For always
We shall
Keep
This joy
Pure.
