Light is too hot and the image is too busy with the web. Perhaps a smaller depth of field and focusing on the spider through the web would have changed this photo for the better.
I can just barely make out that it is an Argiope aurantia or Yellow Garden Spider. The image looks like a snapshot and not very carefully composed. Get closer, much closer! Don't worry, it won't jump off of its web and bite you. The highlights are blown out and the image fidelity is very low, in other words, there isn't a very wide range of tones from light to dark, like the greyscale bar below. The white line on the bottom should have been cropped off.
Spiders and spiderwebs are very hard to photograph IMO since the background has a tendency to intrude. This is happening here, too. There's too much background shining through and distracting, especially the blwong out sky in the top left. Overall the pic is quite bright. Also, I think it would be more appealing to actually see it from the side the spider is on to be able to see the spider better, but I suspect you weren't able to get there.
Btw, since there's the hot discussion going on, I feel spiders are within the challenge guidelines and any score I give is purely based on the photo quality. Just thought I should add that. :)
Like I've said in many other entries, this isn't an insect, but an arachnid. They are entirely different, though they are both arthropods. It is unfortunate that this scientific misnomer is so widespread. As for the foto itself, it would have been better if you got more of the spider's body rather than the silk.
