I love this haiku...The idea of bubbles representing the raindrops, that's beautiful, really pretty imagery here.

Oh, I just love it...simplicity is the key sometimes
:)

This is so pretty. I love the rainbow imagery added in there. :)

And there you go again:)
What a beautiful haiku this is?
Really love it!!

Ok..finding time to breath and finally comment :) I'm always kind of critical of haiku because there is a very small frame to get the message across so...here goes..

Clear circles spinning
prism rainbows mate with trees
bubbles of nature

If you are referring to the bubbles here...I've never seen a clear bubble yet....I guess they are perfectly formed but...I would replace clear with blurred...just because each one is different...they may look the same but..they're not ..like snowflakes...sorry..rambling a little..hope you get the guist of my comment :)
