The rhythm got me besides the crystalline beauty of the landscape as scanned by the poet's eye.

Those snow flakes sound truly delectable in the ambience surrounding nature.
"their bliss romance,
float, twirl and fade..."

They seem to be the right messengers of heaven's message. They are just as delicate as the message is super sensitive. It is only for those eyes that can "see".

Imagery is exceedingly appealing to especially the taste sense.
"sweet bounty from above,
to take shelter on my eager tongue"
It is difficult to catch them on the tongue. Bravo, for doing that.

Season's beauty comes alive before my mind's eye, thanks for bringing out intricate details of a snowflake.

It flows well.

Write on!
