Both my blog and my web site are aimed at beginners. Not because I think I can teach anyone anything when it comes to art, but because most beginners need a lot of encouragement. Beginners get things wrong and that can be soul destroying. I suspect many beginners have given up before they've even started, just because that first effort turned out poorly and they decided they weren't capable. I like to show beginners that it's ok for things to go haywire and that no picture is a bad picture, as long as we learn from it.
Having decided the picture was ruined I consoled myself with a 15-year old malt. I pondered on my drawing and decided that rather than discard it I would think about how it might be salvaged in some way. Rubbing out the background didn't work as I couldn't get a clean enough canvas, so I decided to add 'scribble' on top of 'scribble' to create the impression of field and trees.
The end result is still awful, but it is better than it was. It's not good enough to give to the dog's owner so I shall start over and try and get it right next time. I learned as much about drawing, pencils and Bristol Board during the rescue process as I did before it all went pear-shaped. So my message to beginners is don't be afraid to attempt a 'rescue' when things go wrong; even if it can't be salvaged, find a way of finishing it off that adds to your drawing/painting experience; and don't be ashamed to show your effort to others, nor afraid of the feedback that may come as a result.
Now it's back to the drawing board to start over ... although I may attempt a head & shoulders portrait this time.
