There's one practice to improve your art anywhere and at any time. You can do it any time when you're awake... perhaps even when you are dreaming.
It's the art of paying attention. Of savoring the world around you.
Taste the light.
Become a connoisseur of emotion, of personality.
Look for reflections in the puddles.
A habit of seeing will deepen the essence of your art. It will help you improve your technique. And it may well improve your life.
Happy New Year!
