First question, what kind of camera are you using? Yes, most of the pictures are not sharp. If you are not using a tripod, I would suggest getting one. For picture #14, what is your intent? I think it might be better with mirror symmetry. You can see 1.5 legs of one person and 1.1 of another. If you could see only one of each that would improve the composition. There are things in the background that are distracting. There is like part of a bench near the person in white’s wrist. There are one or two people right in between where you are holding hands with the other person. I would say move up more and just have the gray tile as the background.
For picture #7, is that an artistic filter in Photoshop? I would prefer a nice sharp picture with Forever clearly seen than a picture that is an OK painting. The composition is nice is this pic.
