Create a engagement poster with toon image for couple

I'm looking for an experienced designer to create a romantic engagement poster for a special couple. This poster should combine both realistic and cartoon-like elements, so the designer must have a keen eye for attention to detail. It is important that the colors chosen for the poster be elegant and appropriate for the occasion. I'm open to the designer's color choice, but would love to see their creative ideas. Being creative is essential to the success of this project - because it will be the perfect memento of the couple's engagement.
