This portrait of Mary is based on scriptures. The Catholic doctrine on Mary goes to the point where you have to do mental gymnastics to try to get around the Biblical Mary. What this shows is you can honor Mary without taking it too far.
For about a week I have been trying to get someone to point me to where Catholic Mariology contradicts scripture. I got plenty on how it contradicts various Protestant theological fantasies, but I did not get an answer. May be you can try?
