mod revival drawings.

to kick start my project, i have been looking at photographs from the "Mod revival" era of the late 70's - early 80's

I want to draw these in a style that represents the era or that keeps them in a time period. To create this effect i am using the clothing that the people in the photos are wearing. The people all seem to be wearing parkas. I have started to use this as the main part of the picture and work some detail into the coats.  This idea comes from realizing that by using old photography facial features are not very clear. The parka is used in the drawings to recognise that the people are Mods.
