This should be grown-up Ada, if my "detective" work is correct! May be not...
As a mom of a 17-year-old daughter myself I appreciate that she still poses for you. Love the expression!
Freckled kids keep ruling!
This model looks very familiar! Could it be an all grown up Rowan, I wonder? The style is very Timfythetoo. I love the way the character comes out in this portrait. Possibly slightly over whitened the eyes - dial that back, and it would be perfect.
