Hi
This is a nice family photo. There are several things I would consider that might improve it:
- It's cropped a bit too tightly at her feet and head. Try leaving a little more room so it doesn't feel claustrophobic.
- There's something dark on the left that should be cloned or cropped out. It's distracting.
- Her pose and expression are saying she's uncomfortable and embarrassed. I'd try engaging her is a relaxing conversation of something she loves - tv show, book, major experience, something that gets her expressing herself comfortably and confidently. Then capture the moment.
- Perhaps compose the shot from the waist up(?).
Otherwise, I like the simple and effective composition and technique. It's a good start.
