I think that a good option for you would be good to hire a professional artist with teacher direction.
Perhaps he will reveal the inner talent of the child and send it in the right direction. And lessons with one person is always more favorable for the children. They are not so constrained ... Especially if the teacher literate.
Or reduce the child to master classes for children from well-known artists. Let just look at them. Sooner or later, your daughter will find the right direction. Good luck and creative successes
