IN A VASE - Practice Makes Perfect

By Dyarnell @dyarnell
In two weeks we will be hosting our annual winter party, a tradition my husband and I started three years ago when we moved to frigid but beautiful Winnipeg.  Since I am going to try something new with the flower arrangements this year, I thought it would behoove me to practice. This might sound a little over-the-top at first, but who does not want fresh flowers in their home, practice or no practice?
Over the winter I collected some floral knick-knacks and fake flowers and when it came time to see what they looked like on display it occurred to me that they might in fact help turn a regular bunch of flowers into my own floral displays if I combined them with fresh flowers.
Apologies, but I just did not have the energy to move this where there was a less busy background.  This vase will be in the center of a room for the party which means its shape will have to change so its height is in the center rather than at the back, but these will remain the materials I will use in this vase. 
I am uncertain about the height of the coils, should they be cut back a few inches so they do not tower so high above the flowers?  Or should they be cut back more severely, hiding their sticks making it appear as if they are sprouting up like flowers from a Dr. Seus book?
Let me know what you think.
The strongly scented Asiatic lilies, (the only real flowers in the vase), will have to be white of course since for our annual winter party there is a strict white dress code.
In order to keep the wooden sticks dry I have placed the real flowers in a beaker of water that sits discreetly in the vase which is thankfully still easily watered from above without having to remove a thing.
This vase is quite slim and therefore more difficult to work with since it wants to push all the blooms out its crowded center.Here again the lilies are the only real plant along with some white decorative berries and some silk flowers.
I have realize that I will need to find something for the under story so this 'practice' is definitely paying off.
I am not certain how I feel about mixing in the silk flowers...berries, silver pine cones and the like are definitely okay since they are clearly decorative, but what about the silk flowers that are designed to deceive, do they help to turn this into something special for the party, or do they cheapen it? 
I am undecided so please be free with your advice.
