Picking up the well founded suggestion of cropping differently, here a go with a square format.
First, this is the uncropped image:
As you can see, the overall picture isn't as dark and gloomy as my first try at cropping. I lost a lot of cropping options though, by not paying enough attention when taking the exposure and cutting of that flower on the lower right part of the picture. I.e. my intentions with cropping are in this case: get rid of that mistake in composition and make the detail with the small bug a little more pronounced.
This is what it can look like with a square crop:
Since I found that piece of the tubular part of the flower remaining in the picture on the lower right corner still distracting/disturbing, I tried to stamp that away with the repair tool in LR.
Square crop, version 2:
I think the square crop is an overall improvement (so thanks for the idea), because it removes some of the murkiness or "mud" on the left hand side. Since I rarely print pictures and mostly display them on digital screens, I tend to forget to go for any format that's not roughly screen shaped (that's also why I rarely do portrait-orientation shooting; these pictures just don't work well on screens in landscape-orientation).
A question on the side: is there a way to have smaller previews of linked images in a thread? I find it difficult to get an overview of an image, when it's displayed so large.
