Well, on the upside when I was at church they used to tell us that it didn't matter that we couldn't sing, it was what was in our hearts that sounded good to God.
So, in theory as she did this with the best of intentions and with presumably the love of God in her heart, he should be quite pleased with the outcome.
So, in short, if God doesn't like it then he should have given her better painting skills, and if he does like it then who are we to question?
Still makes me laugh.
