Shop Window Woolworths idea

Thinking about my next steps and although I think the setting of the pub is the most successful and portrays the aim of my project best I still want to explore some different ideas. 
I want to keep the notion of reflection in the work and thought about shop window reflections. 
There are a few scenes in Poor Cow where Joy is walking through the streets which connects to her love for material items, she loves shopping, as for Cathy Come Home the shops and the streets are not a comfort to her they are her home and signify something much darker than what they do for Joy. 
I was looking for some reference photos and thought I would search old shops in Warrington as that's where I'm from and if I'm using myself for reference I thought this would amplify that. I found a site full of all the old Woolworth's that had shut down Link to site and the one above is the one in Warrington. 
The photo was taken in 1970 and I have photoshopped my reflection in the back, although it's small I think this could be successful and I'm interested to see how it turns out as I'm not as familiar with drawing cars or buildings. 

Also I think the notion behind my project of the significance of these films for the working-class works well with my background and Warrington as a place in including these in my work.
