Beautiful work! I find value in posting the trio of images this way, as my connection-seeking mind is more easily able to make comparisons and notice commonalities. Here's my personal interpretation:

The lock and the web symbolize entrapment, namely for the mating flies and their future offspring, though some will no doubt benefit from avoidance or escape. The plants strive to grow within their surroundings, and other human organisms who seek to escape the trap of their environment can express it through graffiti and/or through their music.
All three have that range of light to dark and detail I appreciate from a technical level, anyhow.
I'll be looking for more of your work. Good eye!
