On a serious note and not knowing owt about photography I think the quality and the work that has gone into the shots is outstanding
From a professional point of view, Ken, what makes that shot? Converging lines hitting the concrete curve? Something else?
I really like how the perspective from all the planes in the image are pulled into that one single vanishing point and the differences in contrast in each one make it virtually an abstract despite it being instantly recognisable. There's a symmetry about it having the sharp lines to the left and the curves to the right. I like an image that makes me glance at it in passing, then makes me back up and look at it again. Getting the attention of the viewer is vital. It's hard to tell a story all in one go. First you much make the viewer pause, then you can let the narrative of the image reveal itself to them. There needs to be that hook. The image of the tree blossom you showed me has it. In itself, it's obvious what it is, but then the narrative kicks in and reveals its bot quite what it seems at first. The blossom isn't from that tree but from another one, it was just shielding the ground beneath it like an umbrella from the fall. Unless you pause at first viewing, that story is lost. That, to me, is what constitutes a good image. I don't know much about art, but I knows what I likes.
