Centerpiece help

I need some help with what to do for our centerpieces. We are doing silk florals, borrowed. Below is a couple of pictures of the centerpieces that I ordered. Our reception is small and not a full sit down meal. We are doing a pretty hearty grazing table type thing. The tables are the 6 foot long wood tables and will not have a table cover. I was originally planning to do a wood round with a floral centerpiece in the center of the table and then do three led votives on each end with a sprinkling of rose petals along the length of the table. But I switched the floral collection and these centerpieces are shorter than the others so I’m not sure the wood rounds will work.
I like this look with the candle holders, but I don’t like the metal mix of gold and silver. The centerpiece vase is an antique silver.
What can I do to make the tables look done since they are long without breaking the bank? I’m not sure doing additional votives on each end would look good with this new centerpiece.Thoughts?
