The scribble of the daffodils has a purpose. It whiled away a few spare minutes and gave me pleasure. That is purpose enough. I show it to you to show you that not every time you take pencil to paper does it have to be a masterpiece.
Now, this scribble was done with Inktense pencils, so I can wet the drawing after it is finished and get a more painterly look. It still won't look like a masterpiece - but again - it doesn't have to!
If I really like the composition and think it might well make a masterpiece, I can always come back to my sketchbook another time and use it as a reference for when I want to draw the masterpiece on watercolour paper.
So get out and draw. You'll enjoy it for its own sake. Masterpieces come later !
