Here are some possibilities for you...I was looking at your website and selected complimenting colors. If your layout is staying the same with the vertical left panel the background with the dark gradation made of 2 grays can be a background in that area. It will add depth to the graphics. Also wasn't sure if I was in the correct place I will submit another with the color variations behind the emblem are representative of the fields of flowers
I will be away teaching this afternoon and will check back with you this evening. If you have any direction or would like to interchange elements, try different colors or fonts let me know.
This is similar to your previous logo with a little different movement on the contour of the mountains. Your selection of neutral colors are good since it won't conflict with any photos that you may have in the future. Also The mountain contour is a good representation. I can't show it on the entry but I did superimpose the dark gray vertical panel and the logo here over your wedding page to see how it would look. Maybe you can do that too on all of your entries.
Any adjustments may be made just let me know if you would like to see any alterations.
