Centerpiece help please

Hi everyone! So I’m struggling on my centerpiece! My wedding colors are white and silver im going to post another wedding similar to my colors (same table cloth I’ll be using at my wedding ) and I’m going to post a “trial” I did with a smaller version of my tables in the pictures it’s 60 inch table wedding day will be 72 inch.. in the trial picture it has all the different candles I’m adding and my charges but it’s not the center piece, table size, table cloth or flowers.. I’m going to post my centerpiece flowers and the options for my vase! I don’t know if to pick silver or glass? Thanks so much for your help (my chairs are silver chiavari
