I looked out of the window, and there it was - ominous, majestic and threatening - but at a closer look it turned out to be just unusually dark clouds against the sunset, casting a dark shadow up into the sky...
Nevertheless, to me it looks like an illustration of certain states of mind, like fury - or despair - or anxiety - or maybe a turmoil of mixed feelings...
But if you look closely, you'll see that behind that dark, massive pillar of clouds there is - if you can just manage to get past it, put it behind you, reach the other side - the soft gold of the setting sun, and even a glimpse of light blue sky...
