Hi Brian I agree showing some of the environmental context is important but it is nearly always secondary to presenting the main element of an image as well as possible. I have been looking at your other posts many of which I prefer to this but the two main areas that I think could help improve a lot of your images are by closer cropping and in many cases softer lighting or use of a white reflector giving better detail in any shadow areas. This is just an overall impression I have and softer lighting is definitely not required in this case.
I had tried a crop like yours but to me and I am a little claustrophobic it seemed 'cramped'.
But this morning I went out and found a rather neat insect. i tried the auto program, all of the manual settings and then went inside for my flash suppressor. When i came back i got the following which aside from a 'tight' crop is just about what i took. It was raining and i have found that means i will not get pin point focus.
But I did get good lighting(?) and the crop is tight.
Below is more the sort of treatment I envisage.
