Love the shapes Tom and what you have taken away with you. The unbalance I get only adds by giving a ruffle to what otherwise may well have been a too comfortable, an image.
Love the lighting and subtle colours here Tom. I see what you mean about the geometry and the right hand sight seems bait heavy but not enough to detract from the overall image.
works for me. there's a nice optical illusion going on with the brighter bit in the center, sometimes it looks like it's inset, other times it's popping out from the background.
