In memory of your adoration.

[Achebe]

Shimmering swirls move swiftly as ...alliteration doesn't do anything for this line - sounds pretty forced
light plays across the creek,

Water bends round crooked limbs, ...surely 'the' is needed here, given the 'old fallen tree' in the next line? I might be wrong - just sounds odd to me the way it is.
of some old fallen tree.
 
The sweet hush of the waterfall  ....'hush' is a strange word for the sound of a waterfall
sings lullabies to me. ..not a great line

I hear the whisper of your voice,
the wind that moves the leaves.

Hi Tony - the standout line for me was 'water bends etc.' : it was a fresh, original image. 
given that it's a short poem, you'd like to make each line punchy. 
Also, you've got light, water, water / sound and air / sound. It might be a better idea to have light (fire), water, earth, and air. A neat second layer for free.
good luck.
