If I knew how to edit, I could probably improve my photos somewhat. All that was done to the following was to crop it and reduce it in size for posting.

Well, yes, cropping is one aspect of editing. One tweak that could be done with your pic is composing with the rule of thirds and fifths in mind.
That is, imagine a tic tac toe board. The lines are running in the third of the field up and down and across.
Placing the subject in the third or fifth of the picture is asymmetrical and, by its nature, more interesting to the eye than the formal symmetry of halves and quarters. The fly in your pic, the subject, is running through the horizontal middle, through the "half" line and, therefore, not as interesting to the eye as if it were placed in the third line.
Take a look at any pic in a magazine or clips in any movie and you'll see the rule of thirds and fifths in every one of them.
And the focal point of the subject pretty much always flows into the center of the pic, unless the photographer and/or the editor wants the focus to flow out of the center, say, the end of a sequence where fish is swimming away or downstream. then, the focal point is flowing away from the center.
As far as quantity editing is concerned, with digital cameras, lots of pics of the same thing can be done and then narrow down the images to the optimal number of remaining pics that get the point across. Lots of times the photographer leaves all or most of the pics taken when just a few get the point across in a much more interesting way.
