Not sure what you are asking, so I will ask a few questions:
Interesting sculputures. Where are these?
I assume you shot when you could; mid day is not ideal for contrast and to highlight tectures and details.
Why the high ISO? Looks like you were at the 250-400 range, with shutter speeds plenty fast. I'd shot at 100 and you still should be plenty steady.
But mostly I wonder, why not shoot wider open?
Most of the images would benefit from blurring of the background with a lower aperture value. Of course, you could do a bit of gaussian blur on the background in PS to heightern attention to the sculputures. I'd also try a bit of curves work to bring out details in your last image.
Here's a rework of the last image, done in LR. I think BW reduces the distraction of the color in the background. Curves to darken the background, heighten contrast within the sculputure. And a bit of sharpening. Croppped to highlight attention to sculpture.
Thanks Scott & sbeme. the place is called Brookgreen Gardens in S.C. There are over 900 sculptures & the most beautiful gardens even at this time of year. They also had a small zoo of sorts & going back & forth between garden & zoo, I didn't adjust ISO. I liked the garden settings as much as the sculptures and wanted to bring them both out but didn't seem to work out. Here are 2 more that shows some of the garden. Thanks, sbeme, I love your black/white conversion.Oh and 70 year old body = high iso
