This is my original drawing "Common chaffinch".
Medium: Soft pastels and pastel pencils
Size: 20 x 20 cm
Size framed: 31 x 31 cm
This drawing is framed in a natural 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.
