Pencil Portrait of Parents/Grandparents

I finished the commission for Nancy tonight! Just in time for Christmas! In fact a few days early.  It took me nine working days and about 17 hours to complete (I kept track for the first time).  This is the second piece Nancy has commissioned from me.  Last year for Christmas I drew her daughters.  This year she asked me to draw her parents. She sent me four different pictures in the mail, with requests that her mother's glasses be clear, and perhaps take off a few wrinkles. 

I did my best to compose a good picture from the ones she gave me, doing a little editing on the computer using Gimp. I, however, did not want her mother to be as washed out as she is in the picture I ended up using for the composition.  Flash is such a nasty thing and doesn't make for great portraits - drawn or not!  So, I used the other pictures to help me fill in the blanks some.  I hope her mom looks like her mother.  I think her dad turned out excellent though! 

But, what do you think?  Do you think I did a good job?
