"Patience et Longueur de Temps font plus que Force ni que Râge". (Jean de la Fontaine). Look like in english: "Patience and Time do more than Forces or Fumes".
Wow, you are a gifted artist! This work is exceptionally well done. That is a charming KitKat :) Like this done in charcoal. Very attractive the way you have black on one side of background and color on the other. Wonderful work you've done. It should get the highest marks~
