This is my original drawing "Long-tailed tit".
 
Medium: Coloured pencils
Surface: Fabriano hot pressed aquarelle paper
Size: 15 x 15 cm
 
This drawing is framed in a warm wood frame with museumglass. This protects the drawing from UV (makes it last longer) and reflects a lot less than normal glass.
 
All my drawings are made with high quality materials. Which means the drawing will last a long time without fading colours.
