Update 2: Please make design black and white (or a single grey and white). In the sample images, various shades are created using varying spacing between lines. Please see the attached file "black and white lineart".
The reference to catholicism should have the following meaning:
Rose (a symbol of the virgin Mary) and the Dove (a symbol of holy spirit) should be embracing the newly wed. i.e. not simply add a pair of wings to the Gs, or add a Halo on top of the G's.
The catholic symbol should have greater emphasis than the letter G or G's.
1. Couple's names both start with 'G', please incorporate two G's or g's in the logo - G can 'hide' behind logo, or semi-transparent over the logo etc.
2. Please incorporate subtle catholic meaning to it, e.g. dove representing holy spirit, sacred heart, rosary, angel, etc. Please not be too obvious, not one big cross + two G's.
3. Monochrome, use lines to create shadows to achieve a 3-D effect. Please see attached files for example of using lines to create something 3-D.
4. Classic, sophisticated.
