This photo needs improvement because it is too dark. There needs to be more light on her face because you can't see her eyes too well and her features create strong shadows. Also, her hair blends right into the background, making her face look like it's floating.
This photo needs improvement on the angle. This was taken at an odd angle making it unattractive to look at. If this was taken from an aerial view or at the same level as the piano, the photo would be much better.
This photo needs improvement because it has a cluttered background and is boring. If this was taken against a simple background, the photo would be more appealing and less distracting. This photo is also boring and dull, if it was taken at a different angle or the shoes were positioned differently it would be better.
