Give your child a pencil and paper. Observe how they work with it. If they begin to enjoy it, you will have a kid who is interested in art. Kids who are artistic in nature have a very strong imagination. Such kids are also creative because they put their thoughts on paper and make beautiful drawings from it.
Join your child while they are creating artpieces. You can give inputs and appreciate their creativity. This will motivate them and they will do better. If your child turns out to be extraordinary with pencil and colours, this can prove to be an amazing career opportunity for them. They can be the next Picasso if you push them to do their best.
