Abstractions of Snow

Is there really such a thing as true abstraction in art? I observe myself in this snowy weather unconsciously reflecting the soft, quiet shapes of the snow in my drawings this week. My studio is freezing and feels very open to the outside and exposed to the elements. As I sit now in the warmth of the Rayburn I recall the blizzard of flakes that fell on me during a walk this afternoon and know that these informed my
 drawings and were just abstracted memories.
