Thanks. I seem to understand my shooting style problem better now - I constantly have the problem with my pictures having no central point of focus. But it seems so hard for me to correct that problem. Sometimes I simply shoot a seemingly beautiful scenary but is unable to find a subject. Any further advice for me?
I think what make this scene attractive to you is the golden light - the sun's setting right? - the leading line, and the overhang on the river bank. You have positioned the latter at a natural focal point - about a third from the left edge - in the frame.
What is missing is a subject there.
And if that is so then there are extraneous elements you need to drop from your composition - either at the time of capture or via cropping after that - namely the white building in the far background and maybe the guy in blue in the left forground. And to adopt a maybe 2:1 format ration to emphasise the lines leading away.
In other words, as it is, there is no picture for you to photograph as yet - the quintessential photographic moment is not there yet. You need to wait for some happening on the overhang, and only then shoot. Or you put some one there.
But of course this is in hindsight. What you need to do is to practise seeing a picture in your mind before you shoot it. And with a digicam such a practice is easier than ever before - you can just shoot, preview, and do a self critique: asking yourself whether it is a picture or not. And then reshoot. Only be sure you dont miss the Kit Kat moment when you are busy previewing and not looking at the scene when it happens.
Photography is all about timing. Unlike a painter, you are not as free to put elements in - or out - to make a picture that you saw or visualised. You have to wait for that moment.
