I’m very fortunate to have three friends that I’ve known since early childhood; it’s wonderful to be able to share such a long perspective on our intertwined lives. We met this weekend to celebrate Si’s 50th birthday with a walk through the Cotswolds, and a few drinks. I sketched in coloured pencil while we walked through the woods, occasionally stumbling over tree roots… (adding the light wash when we stopped) and also at the destination pub with my trusty bamboo dip-pen. Many apologies to all three subjects for the portraits, but especially to Steve for the tiny arms. Many happy returns!
Mostly drawing 
Drawing while walking sounds perilous! At least you weren´t dipping… 😉 What a treasure to have friendship like that. It looks like you caught some of their character here (I say boldly, without knowing them).
The rear views of them walking are the better likenesses, through body language and shape. The pub ones are very rough, they would keep moving!
You have captured a great likeness of my father from behind. I have heard that it happens to most sons. I do think you have captured a likeness of our posture and gait.
Cheers Douglas! Fun mementos of a lovely weekend
