Cropping
I like the middle photo of the dog because its taken from a different angle then what you would normally see. The top photo of the sunflower isn't my favourite because the petals are in focus, however this does make you look more that the centre of the flower which is in focus. I like the bottom phpoto because i had a shallow depth of field which made the back ground of the photo very blurry, which means there is nothing distrcating in the background.
