AUnified Truth: The Celestial Visitor

I need to create a cover for a book. The image of the Virgin Mary, with a gray alien face and with open arms as you see in the attached image, the pose is the classic welcoming one. She has a serious expression, She is dressed in light blue. From both hands comes out water, a flying saucer appears above her. Image must have these dimensions 6” x 9” (152.4 x 228.6 mm)
