Many thanks for your comment, but I don't agree! ;-) I'm very particular about every aspect of my images, and if I thought it looked better with a crop across the top, I would have done so! I experimented with it, but I think in photographs it is important to let the subject "breathe"...and to to me a crop reduced the effectiveness of the tyre. But if you think it would look better, then that's cool, vive la différence! It would be boring if everyone felt the same.
