Assignment 2 ...selecting images for 'On the doorstep'

My objective for Assignment Two was to capture the group activity of political canvassing on the doorstep by following a group of canvassers at work. I had in mind the kind of activities that happen when out canvassing based on my own experience so my aim was to look for and take images illustrating the following : 

• team assembling / briefing
• working the board*
• response back to board
• door knocking
• talking to voters
• walking the street
• interaction between canvassers - 'cameraderie'
• individual or groups at work
• post canvass wrap up 

* The 'board' is the list of voters in any street or block of flats and is used to direct canvassers to which door to knock on. 

I went out a number of times with the group until I felt that I had achieved a good range of images within my key activity areas - this meant a large number of images to sort through and rate. Deleting the obvious poor shots that can happen when shots are not posed in any way  (e.g. last minute movement, poor lighting, eyes shut etc. ), I divided images up by activity and rated then within the activity.

Rating images has proved an interesting conundrum. What criteria or combination of criteria to use when rating e.g. composition, technical quality, how well the activity is explained , whether it is a ' telling moment' ? For example :

P871

P863

Does P863 or P871 better demonstrate the speed of street canvassing?

P868

P867

Or P867 or P868 below the working of the board ...

P872: F18  @ 1/1000  18mm  ISO 1600

How  important is continuity of images going to be ? Does it matter that my board man wore a red jacket on only one day....it lends some good branding colour but will someone viewing a mix of images from other days notice that he is wearing a different jacket and think more about this than the 'activity displayed ?

At the end of the day, my final selection focused more on how well I captured the activity (which involved assessing composition) than on those images that were better technically but either less interesting or expressive of the activity.
For example, I liked the image below from the point of 'atmosphere', the expression in the  direct look into the camera of the canvasser waiting on the doorstep for the door to open. But as a rather static composition, it didn't make the final cut.
