The girl's hair is underexposed, leaving it mainly a textureless black mass. There is a nice rim light to seperate her hair from the guy behind her. The stray hair on her face is not attractive, especially the strands across her left eye. The background is jumbled up with people. They are too in-focus and distracting. I keep looking at them instead of just the subject. I realize this is a candid outdoor portrait, but you might be more careful with the details.
The third image is just a bird. Nothing very special to set it apart. The bird's beak is out of focus. Somebody will like that because it adds depth, but ... . The bird is a very mature subject Lot's of bird iamges) with a very immature image. There needs to be some interest - reason to look at the photo.
