Portrait of little boy

I have a got a friend(Chrissey) at work, she always loves my pictures, she brought up this picture of a little boy she said was her grandson.

I loved the play opf light on his features and I made a 2 hour sketch of the picture she provided.

This seemed to be one the first times that I didn't need to scale the picture but I just went direct with intuitive measurements and it came out quite ok.

Chrissey loved it
