Uh, not really sure what to say. The only thing you have looking at the camera is the dog.
Unless you have a hair fetish, the first three images are not too interesting. Great hair detail in #2, but the subject is just hair.
the girl with the bubbles is cute, but you have her so far on the side of the frame...move her a bit more towards the middle and get in closer.
Remember that when trying to convey a thought or emotion to a photo viewer, you as the photographer need to take everything in the frame into consideration...the subject, the background, the exposure, the colour, shapes, textures... this all helps in telling your story.
When shooting living beings, the key to interest is usually with the face and more importantly with the eyes. Backs of heads are boring. How many great sport shots have you seen that dont have the athlete's eyes in them? Probably a few, but they are a minority.
You said it was a festival, but nothing shows me what kind of festival or what was going on. When doing journalistic shoots like this, get a mix of those "crowd shots" that help you give the viewer an idea of what is going on. Supplement that with emotional (funny, sad,...whichever) candid shots of people, closer in the frame.
