70s Prisoners and guards

I need ten faces created for a game - five prisoners, and five guards.

These need to be finished as SVGs if at all possible, and in a 1970s style of flat cartoon - think Flintstones.

Faces should be forward, prisoners wearing stereotypical prisoner hats, guards wearing guard caps.

There should be discernable differences between the faces, a scar on one cheek, unshaven on another.

All should be male, and skin types can be diverse.

The faces will end up as images approximately 16mm tall by 20mm wide, but obviously I will have bigger.
