Maybe it's just because I have zero-ability to even hold a pencil, but simple well-executed sketches and illustrations always amaze me.

Illustrator Aurelio Madrid creates beautiful graphite sketches in his "Small Portrait Series". ... and if you look closely you might even find a couple familiar faces.

If you appreciate these, be sure to also check out his Post Photo-Realism gallery.

Aside from illustration, Aurelio also keeps a couple of blogs for your viewing pleasure. ( Wordpress | Tumblr)
