1. My favorite photo is the first panorama that is shown. Its the one of the beach with the surfer in the right of the frame.
2. These images look like they could have been taken on a really nice camera. It doesn't look like they were taken on a phone.
3. I think the apps if any did indeed help the photos look better, but I don't think it affected them that much.
4. Two tips for my own phone photography:
- creative composure in the frame
- clear subject/focus point
