Help experts analyze four pictures from a photographic point of view? ... thank you very much

One piece, the picture is informative and messy. When composing a composition, you can use a vertical composition, and take the younger sister holding a mobile phone to take pictures as the main body of the picture. If the viewpoint is lower, it will be more interesting to take a photo of Miss Jie taking cherry blossoms.

Two films, the perspective is worthy of scrutiny, the characters are dynamic and tensionless, slightly in the middle.

Three pieces, side backlight, too many shadows on the characters' faces. Background framing can also be considered. As a general portrait photography, the scene is slightly complicated. As a souvenir photo, the framing is not enough and the environmental elements are not clear enough, which makes the photo look too ordinary and plain.

Four films, the weather is good, the light is good, the composition is slightly too loose, the main body of the view is too centered, and there is room for deletion in the secondary composition of the picture.
