In this image, I felt that the subject (the cocktail shaker and glass) was not strong enough, with too many distractions, so I cropped as shown to produce the image below.
Overall, I think a stronger image has resulted.I looked at cropping further, but as the photo was taken in quite low light, a significant amount of noise started becoming apparent.
The next image I took because I liked the greens of the lady's blouse being "reflected" by the green of the limes. Again, through cropping, I am looking for a stronger image.
The crop has removed extraneous parts of the photograph creating a cleaner image.
In the photo above, the image was not really finished in my mind and again, the tighter crop has dramatically improved it.
