This is something I need to do more of. My focus is landscape which often is busy with lot's of details. So images like this are something I don't often do or in a position to do. Or perhaps my eye just doesn't see them. But I find them very artistic feeling, so I would like to find them and capture them more then I do.Thank you for your kind comments. I've always been attracted to photos and artwork which make use of negative space. Sometimes I think less is more interesting.
