With a shot like this you really need to get in close to isolate your subject from the cluttered background -which should have a shallower depth of field in this case. The main subject of the shot is the spider and web, but it does get lost amidst all the stalks of grass. If you were unable to get any closer when you shot it, perhaps you can zoom in on it in photoshop and then crop it so more of the spider and web show. Its a shame that the one stalk of grass is coming down straight over two of his legs also. With a little work, you might even be able to clone that out in photoshop.
