It's annoying-but-true that it can be a good thing to screw up. For about two hours, I was satisfied with my first attempt at these bugs from my Insect Alphabet. Then I wasn't. A green grasshopper against a green background may be good camouflage in real life, but it doesn't make for a good picture. Ditto for the fly, who seemed to be floating in mid-air against a weird background--a dead fern and a stick. What's that all about?
Getting it wrong forced me to stop and think. A plainer background, in yellow and brown, would make the grasshopper stand out more. And if I put the fly on a plain white background, it would look as if he was crawling across the page (or screen.) Because I lead a sheltered life, this struck me as brilliant and hilarious, and I thoroughly enjoyed doing that revision.
It just goes to prove, for the umpteenth time, the annoying fact that getting it wrong can lead to getting it right.
