No postwork here, but I tried to slow down the movement with the new object. 
What do you think?
Hi Kathy,
Nice image composition. Did you try to activate Shadows? I think the image needs softening with subtle light and shadows.
Make sure that at least on of your sun lights has shadow selected and increase the intensity and the length.
Then activate shadows in the render panel.
You will know it`s worked if the ants cast a shadow on the wood.
If you don`t understand any of the above let me know and I will do a step by step.

I of course enjoy everything you post here but Gurgler’s and Southern’s suggestions are great. Your roses are beautiful and I bet they smell as sweet.
Thanks southern, I get it. I just gotta do it! (appreciate your expertise).
I’ll be back (The Arnold)
Your gettin’there Kathy-the railing did stop the dancing eyeball syndrome,the roses are
very nice.Did you build those in ZBrush?
Yes, I did. 
I’m going to put the rose ZTL on my downloads page.
So, just to fill up the server (sorry Pix) here’s the last render with Southern’s suggestion too.
This is neat!
