OMG, Joe! Those are crazy good! You know how I feel about the wonky teeth, so I'm sure it will be no surprise when I add that the 2nd one makes me want to weep for happiness.
Truly, these are so addictive they should be grouped with gambling and narcotics and original series on HBO. The only answer I can see is to make a bunch more and trade them with everyone who's going to be in New York . . .
Yep...what Joe said..in spades. This is what I do instead of knitting or a pen and ink "normal" sketch when out and about. I blind draw faces in the crowd...and no one notices becase I don't drop my eyes to the page! Stealth sketch mode!
