finished that picture! However, finding a new image by cropping can feel very creative, and rather satisfying too, particularly if the picture is bugging you, or doesn't meet the demands of your "inner taskmaster".
Of course, if you had started with a good thumbnail sketch, you probably would never need to resort to such drastic action - but then again, even with the best will in the world, we sometimes find ourselves (I am talking about myself here, I realise.........) dissatisfied and wanting to make changes.
As you can see, I did finish this image, called "Fixing her hair". But I was never really happy with it. Although I rather liked all the interesting echoing angles within the image, I just did not like the girls on the right of the picture. So I have tried a crop. The resulting image pleases me more, but I still do feel I should have spent more time on my original thumbnail! It is an image which will never see the light of day. It is quite fascinating and revealing tho, as an exercise, to see what a crop can achieve and the change it can make to the atmosphere of an image..
