Nice, and interesting, shots.
I am a beginner, but I assume that you see the depth of field situation as 'soft focus''? (where the camera can only focus on a small area).
If so, it is a large part of macro work is about making the most of DOF, or limiting the effects of it. The clever guys here manage to do just that. Some use focus stacking to make impossibly good shots.
One of the good things about the shots you posted is that the background is 'out of focus', and that makes the subject stand out, which makes the whole picture work. For people of my standard, that is the main aim, get the subject in focus and lit well enough to capture it.
If I misinterpreted your 'soft focus' comment then please ignore this response
