Probably not going to win you any awards, but you never know what some people consider to be art!
You could probably find someone who would speak about the photo being a metaphor for life, or "the struggles of the artist as an organic creature in an artificial world" or some such nonsense.
Hell, I'll write it up for you for a few SBD! 😂
I myself do not know what to think, like empty. whether awards or what batteries do not care. the most important thing I am happy without having to hurt others
