"And Son..." - Influences for Barnabas and Family Dynamics

I have been looking at father-son images trying to catch the dynamic between a dysfunctional father-son relationship.  Most images are stock photos, and whilst they use exaggerated actions to suggest emotion they do not actually capture it in their expressions.
We don't want an exaggerated over-obvious statement between our characters, everything is conveyed with  subtle, natural glances, so I will be life-drawing this week!

Outfits for Barnabas are simple to find - funeral directors have not changed their traditional dress since Victorian times!
