Thanks, Lonnit and Traveller. I have tried several different crops; I thought it would be better to position the top right corner of the inner square according to the rule of thirds but the result was by far not as good as expected so I decided to keep the original entry. -Gerald
I believe I would have been tempted to have cropped it along the edge of the unit, which would have left it dull, and I probably would then have just trashed it. That triangle of sky adds interest and impact, giving a bit of energy to what would otherwise be a stagnant image. Well done. :) ~ Lonnit
