Mike this image is on the soft side a higher shutter speed would have helped you had plenty of ISO to work with.
Also if the twigs bother you take some time and PS them out if you want. Also the image is cropped a little tight more room in front and higher in the frame would be better.
Good capture with that bug but so many twigs really hurts your subject. I like Tims repost!Nice and clean! When working with that 600 mm focal length....Remember the rule ....your shutter speed should be equal to or greater than the focal length. Also when shooting at that focal length it is important to brace your camera somehow. That magnification will be affected by your breathing or any slight mistake in technique
