Thank you for liking my swans.
My reference was an ad for White Swan papers products, but I did it about 10 years ago and they do not use the same ad now. It is a Canadian company so you might be able to see it at the library in a Canadian magazine of around 1991-2.
The original was of a swan and her 3 cygnets.
I painted it by eye, and not with a grid or tracing. It did not turn out that well, in fact the two little cygnets were the best part of it.
I'm nervous about copyright restrictions so I won't post the whole painting, but I will try to post an enlargement of my tinyhead.
They are beautiful creatures, and I hope you have fun painting them.
Hope this helps.
