To me it´s about how u choose to display the choosen subject, There are many diffrent guides as to how u can do this and when I studied digital imagemaking at university we got a bunch of papers with rules as to how u can work with composition. There are of course some general rules you can use, like the rule of thirds, the 3 rooms: fore, middle  and background. But these are not rules as such that you allways have to use them. I got a comment awhile ago about the lack of focal point in one of my images, it made me think since there was not a shap focus anywhere in the image, but for me there was a focal point that invited the eye in to the image so I guess that we all see according to our image-base. For example, I draw alot and looked at images of da-vinci and that type of images, when coming across picasso I couldn´t in anyway understand how people could raise him to the skies as one of the greatest painters. But getting to know the history and by seeing other artist that bridged the gap between Da-vinci and Picasso I can understand and appreciete both.

In some way I guess that is true for photos and compositions too, the more images I see, the more I can appreciate images that break away from my normal preference.

To sum it all up, there is no sure compositionsalway to get a good picture, but a good picture has allways some composition
