It's not a bad description of this kind of illustration. I don't know why, but I sometimes felt it was a bit of a slur. Whimsical. Made me sound less serious. Not that I am serious, but you know what I mean. If I remember, this was drawn for a Japanese client. Used to get lots of calls for character illustration from Japan. I called this character Mr. Leaf. The thing about this pencil technique, it suggests more than it explains. Sometimes it's hard to suggest something implausible with a concrete line, if you follow me. But the eye takes a pencil line on faith. I guess that's what makes it whimsical.
