Here is one I made for somebody's niece.  The guy who bought it is a regular customer of mine.  It is a pain to make custom ones for people, because then I have to focus on just one for an hour.  Normally I like to work on thirty napkin arts at a time, painting a little here and there, and letting them grow organically.
 

     These two I made because my friend Charlie pointed out that I didn't spend a lot of time on hands on my paintings.  So I did these just to show I could draw hands if I wanted to.
