I definitely enjoy poetry about winter and did like the imagery that this piece provided. A few things bothered me. The adjective "blithe", while correctly used, was a bit harsh on my hears and felt more like a hindrance to the rhythm than benefit. "Branches" are coated "by" may work better using "with", because it makes a bit more sense that something was coated with a substance, rather than by it, (unless the thing doing the coating was mentioned therein). The word "frigid" is also misspelled in the last stanza. The phrase "has now" doubly implies the presence of winter, and could do without "now". Overall I feel the author did a good job.
