commission portrait 16"x20"

Haven't done a pencil portrait in awhile.  They are always a challenge.  Funny thing is that if i know the people, I seem to get the portrait right quite easily.  Must be something subliminal about it!  These lovely people are the parents of one of my oldest friends who are celebrating their 60th wedding anniversary.  This drawing is of them at their wedding 60 years ago and then at the lower right will be their present day selves.  My friend's Dad commissioned this gift as a surprise for his wife.  Man, is he going to get major points for this!!  I'll post more as the drawing progresses.  There will probably be changes as I go along, so see if you can detect them.
