Construct a collage surrounding the theme of a wedding. Please include an ample outdoor venue adorned with white lilies and tulips, under a clear blue sky. Incorporate a tastefully decorated altar with a white linen canopy and gold accents. Also, display a table laden with fine cuisine and a three-tiered wedding cake decorated with cream frosting and a touch of navy blue ribbon. Add in some wedding attendees - an Asian groom in a stylish navy suit, a Caucasian bride in an elegant white lace gown with a long flowing veil, a Middle-Eastern woman in a vivid pink dress, and a Black man in a charcoal grey tuxedo. Please include a rosy-cheeked ring bearer and an adorable flower girl, both of Caucasian descent.
