Parent working w/child on scale model toy

We are looking to create a campaign that shows foster parents sharing their passions with a foster child. One of the main themes that we're highlighting foster family building a scale model building together.

We need images to show both a foster child or children and the parent(s). Diversity is important. The foster parents can be different ethnicities than the children and that is likely preferred. Overall, we'd like a good ethnic mix if possible. Creatively, we want these to feel like a snapshot of life where the child is learning/exposed to something new for the first time. Good use of light is very important.
