Idea

When I was posting about Sadie's painting, yesterday, I was struck by the things I saw in her picture from looking at it on the computer.  There is a fairly obvious triangle formed above her nose, down the sides of her muzzle and up to the place between her eyes.  There is another triangle that is upside down and above the first one that is from the top of her head down to between her eyes.

Funny, I did not see these before.

For a couple of paintings, I might try to do a drawing before painting where I:

• Draw the outline.
• Look for a mark key shapes. 
• Do some shading to reflect the values (lights, mediums, and darks).
