you have good balance on the image, meaning you showed the right amount of sky and and the vine. The barbed wire gives your compostion a different view.
hmmm .. I need more of a focal point subject .. the quintessential bunch of grapes speckled with dew. Minus the grapes, I'd settle for the gnarley wood of the vine itself .. and minus that, I'd settle for whatever you chose to share with me
I live about 50 miles or so from Napa Valley in California and I know that there are some magical times to visit the area (spring, with the mustard plants and wildflowers growing between the vines) .. as well as some times to avoid (those that feature more fruitflies than oxygen)
