The brief is a bit confusing.
Need to explain the work in more details.
Need to have some text.
The window glass is multi bright color and the type of example you provided are mat color.

We are hoping to have the final design use the colours, and styles of glass design that are shown in the 2 attached Sagrada Familia pictures.The text should be sample wedding invitation text - 3 samples of possible text have been attached (files Preview/Preview1/Preview2). These were samples of the text style/sample content only - we would want stained glass imagery incorporated something like these.
