IAP A1: request for critique

I would be grateful for any comments on the images below, which are a work in progress in response to Identity & Place assignment 1, which asks us to make five portraits of five different people from our local area who were previously unknown to us. The reasoning behind my presentation of the images is available elsewhere on my blog, but I am showing them here without explanation and am interested in hearing what the presentation/s signify to viewers and whether the two formats differ in this respect.

The responses I received to my request for comments can be read here.
