My uncle matts painting of me

This is a painting of me when I was 3 . I was sitting on my water seal and I was in a bad mood. So my dad took a picture of me and sent it to my Uncle Matt. He's an artist. Once we sent it the magic begun. All he did was draw me with a fat vivid then instead of painting he used a stamp with my birthday on it. Every artist has a symbol. My uncles symbol is 66 it's in the corner of my painting. 

This is the photo he copied.
