Marleen,
Thank you for looking and commenting.
I rather like the (tiny, but bright) splash of intense color in the otherwise very muted color scheme. I think their mass on the lower right balances the mass of the tree on the upper left.
I had very little "wiggle room" in this composition. What can't be seen in the image is the wall of my house just inches out of frame to the right and a support column out of frame to the left. I essentially was looking "down a tunnel" toward the fence and had to accept that narrow perspective with the (then) flowers in their position.
But as I said, I like them there. I didn't like any of the (very) slightly different angles that I was able to shoot.
