Originally posted by groesener I'm not happy with the haze in the upper right, but don't know how to avoid it.
Shading the lens (using hat, hand, assistant, or even a Flare Buster) will do the trick as long as the sun isn't actually in the frame.
At this size the bushes are plenty sharp. Unless you're planning to make a very large print, don't worry about how it looks magnified to 100% on your monitor. At f/8 you certainly won't have everything in focus. You could stop down a little more, just be aware that at or beyond f/16 diffraction softening takes a toll.
As snappychappy says, a nice image.
