Get those brushes out and create a visual record of yourself by painting a self-portrait. There's no question about it - the clock is ticking...and you're not getting any younger!
A portrait is more than a photograph. It has a certain "qualite emotionnelle," a softness or sense of "other-worldliness." As an artist, you can be the editor. Don't like those wrinkles? Leave them out. Want to take a few pounds off? Paint yourself slimmer. Or if you're a realist, capture the actual truth by painting yourself as you are - warts and all.
Just think, in ten years you'll look at your self-portrait and say, "I was so young then..."
If you paint from a photograph, make sure it is a good one. Don't use flash photography because it washes out the color and form. Use a strong light source if you want a little drama. Make sure the light comes from above (it looks more natural that way) and that it passes transversely across your face. This will create shadows that show-off your features and describe your form.
Set up in front of a mirror and paint from direct observation. It doesn't matter how you do it, the point is...to begin painting.
