When you click on him,
you see him twice
his original size: cool!

You've got to guard against repeating yourself. Especially with life drawing--the kind of life drawing done in public. If you only get a minute (or less) to look at your subject (and you can't stare!), you are working as much from previously knowledge as what you are seeing. Like this guy. I saw his whole head and thought, oooh, that's a good head!

But then his lunch partner sat down and blocked the lower half of his face--and to cap it off, he put on sunglasses. So I had maybe a 10 - 20 second look at him before "losing access".

The result isn't bad, but from the bridge of the nose down it wants for specificity.

And a sideburn.
