"Will you walk into my parlor?" said the spider to the fly; "'Tis the prettiest little parlor that ever you did spy. The way into my parlor is up a winding stair, And I have many pretty things to show when you are there." "O no, no," said the little fly, "To ask me is in vain, For who goes up your winding stair can ne'er come down again."
"I'm sure you must be weary, dear, with soaring up so high; Will you rest upon my little bed?" said the spider to the fly. "There are pretty curtains drawn around, the sheets are fine and thin, And if you like to rest awhile, I'll snugly tuck you in." "O no, no," said the little fly, "for I've often heard it said, They NEVER, NEVER WAKE again, who sleep upon YOUR bed."
Said the cunning spider to the fly, "Dear friend, what shall I do, To prove the warm affection I've always felt for you? I have within my pantry good store of all that's nice; I'm sure you're very welcome; will you please to take a slice? "O no, no," said the little fly, "kind sir, that cannot be; I've heard what's in your pantry, and I do not wish to see."
"Sweet creature!" said the spider, "you're witty and you're wise, How handsome are your gauzy wings, how brilliant are your eyes! I have a little looking-glass upon my parlor shelf, If you'll step in one moment dear, you shall behold yourself." I thank you, gentle sir," she said, "for what you're pleased to say, And bidding you good-morning NOW, I'll call ANOTHER day."
The spider turned him round about, and went into his den, For well he knew the silly fly would soon be back again: So he wove a subtle web, in a little corner sly, And set his table ready to dine upon the fly. Then he came out to his door again, and merrily did sing, "Come hither, hither, pretty fly, with the pearl and silver wing: Your robes are green and purple; there's a crest upon your head; Your eyes are like the diamond bright, but mine are dull as lead."
Alas, alas! how very soon this silly little fly, Hearing his wily flattering words, came slowly flitting by. With buzzing wings she hung aloft, then near and nearer drew, Thinking only of her crested head - POOR FOOLISH THING! At last, Up jumped the cunning spider, and fiercely held her fast. He dragged her up his winding stair, into his dismal den, Within his little parlor; but she ne'er came out again!
And now, dear little children, who may this story read, To idle, silly, flattering words, I pray you ne'er give heed; Unto an evil counselor close heart, and ear, and eye, And take a lesson from this tale of the Spider and the Fly.
Heidi, the particular web you have selected for this shot is good, in that it is large, it is well placed with regard to the light source, and it even seems to have small drops of water in it (if I see correctly). The problem is, I don't see a single spot that would be in focus! If a picture of such a delicate thing as a spider web is to work, it needs to be absolutely sharp, IMO.
Another thing I'd suggest would be to move even closer to the web, because its structure is what I think you should really concentrate on. In this pic, you have plenty of space all around the web (except at the top where a bit more room would be OK), which hinders that concentration somewhat. If your camera can't focus from a closer distance, perhaps you could crop the image differently.
The lighting and the background blur are quite fine, and I like the story that you've supplied with the pic. If you can take this shot again, with more work on the sharpness and the composition, you'll have a very nice image.
