Is it because I love the story that can be told from the back or side as if you're looking in on the story? That's an answer I've given.
I think, however, that's only a partial truth. I think the more accurate reason is that faces are just plain hard!
The challenges that come with making a white canvas look like a specific person keep me humble, remind me that my skills are limited.
I "finished" this precious little girl a few days ago; however, I could tell from my husband's polite reaction, that it really wasn't finished. Because I was frustrated with her for not cooperating, I literally put her in the corner for a few days.
With fresh eyes and spirit, I put her back on the easel, turned her upside down, and went began the plastic surgery... cut off some hair, lengthened an eyebrow, lightened a cheek... fattened a lip, lowered a chin..... almost. But she needed one more go... squared a chin, added some mascara, highlighted a nostril, deepened a crease...
There comes a time to say, "I'm satisfied. I love her. I love the story this image tells."
This final stage is like editing - looking for what's wrong.
There are several strategies that I use to help me "see" better.
** Leave the room and come back. When I imagine seeing it for the first time, I can be more objective.
** Ask a friend what they notice first. Usually if something jumps out first, it's shouldn't be there.
** Take a picture of it, and put it on the computer screen. It's like a fresh view where things show up that I just wasn't seeing on the canvas.
**Look at it in the mirror. Sure the reflection is backwards, but it's amazing what I notice that I didn't see before.
**Turn it upside down. This takes the "person" out of it and just lets me concentrate on colors, lines, and shapes.
