Analysis of A Chilly Vision

I gazed through an iced crystal pane
Looking at three winter backdrops:
A tree is struggling under snow
Its maple branches drooping low.
Two small flowerbeds are asleep
beneath very deep, white blankets.
As I gazed, I became entranced;
All of the snow had disappeared
Revealing the presence of spring-
Tiny, green protuberances
appeared from numerous branches;
Rudimentary daffodils
and tulips rouse from their slumber.
Then I blinked twice and all was gone;
except my yearning thoughts of spring.
