Part TWO: Element of Design --- Exercise - Positioning a point

I thought this exercise would have been fairly simple, but it was not really!

1) I first went to a park intending to take some photos of some birds in water or on grass. When you are on the same level of the subject you want to take, the subject won't appear as a point. Instead, it appeared to be occupying a lot in the frame therefore it was not a single point(!)
The image below shows two swans in a pond. Because they are quite next to each other that they look like a single point (?) The swans are quite distinct and the background is quite blur. You should be able to draw your eyes to the swan instead of the background.
OK in this case I framed the subject toward the centre too much. It is not on the 1/3 of the frame so I cropped
This image was cropped so that the subject sits on 1/3 of the frame but is it small enough to be a point(?)

2) I finally took some photos of birds on the grass but I wasn't sure how small the subjects should be to be considered as "single point" in a frame(?) I used zoom 100mm fixed focal lens so the subject was not close. Is it too far?
(NOT cropped) (CROPPED)so the subject look bigger comparing to the frame but still is it big enough to be a point(?)
The foreground is empty so it might look quite boring but that could draw attention to the bird itself and nothing else!

3)I took this photo when we went to the Wetland in London. We were in the HIDE but I ended up taking a photo of some cow!
Taking photos from above does make the subjects more like "a point" with an open background. This image is not so plain and boring because the grass is quite tall therefore it adds texture to the image. The red cow colour gives a bit of a contrast with the green field back ground.
I did not have to crop this image, fortunately. I think it was OK as is in term of positioning in the image.


Conclusion:
Positioning a point-
a) size of an object to be considered as a point (?)
b) left or right - the orientation of an object makes the positioning different. for example of the cow image, the cow is facing into the frame whereas if I place this cow to the left hand side, it would have looked like the cow is leaving the scene, hence it might have looked different(?)
c) top or bottom - I still prefer a point in a frame to be in a lower part of the frame if there is only a single point there.
d) I sometimes couldn't get the positioning (compost) of the subject right at the time of shooting. sometimes it's because the subject is moving so I just had to quickly make a shot and crop it therefore cropping often comes into play of positioning the final image.
to get it right first time would be an ideal though!!
