Title • at the water's edge

The more I've looked at this shot, the less I've liked it – there's something about the lighting that's not quite right. But I guess that's the difficulty with the image-a-day thing; sometimes it's just not possible to take enough shots that you're entirely happy with. Which begs an interesting, but probably unanswerable question: why is it that sometimes you can go out and effortlessly shoot images that you're happy with, while at others, despite your best efforts, it seems much more difficult to come up with anything even half decent?
