The absence of the stars on the Mother of God is a serious omission. And I do have a problem with work which is made to resemble icons, but is intended as "art". It's one thing to have a print of a Renaissance master, or other non-iconographic art and to know that it can be admired and enjoyed for what it is. Nothing at all wrong with that. But when a work looks like an icon, but isn't, or isn't quite, then regarding it as "art" blurs the boundaries.
Great care is taken by hymnographers to write hymns and prayers which accurately reflect and proclaim what the Church teaches and believes. I would feel uneasy at the thought that an Orthodox Christian would choose to display an "iconographic" image as "art", knowing that the image is deficient as an icon.
See what I mean?
