It tries to match real art because that's what it's been fed. Sometimes you'll even get hints of watermarks in your images. I do think though that the "style" in this case is less the choice of colors, or shapes but more "how it blends" elements together. Midjourney always has this smeary, no straight lines, rounded look. It has a general idea of what it needs to draw, but it "draws from memory". Like if somebody tried to draw a horse without reference. The core elements are there, and you can either clearly see what it's supposed to be or what it tries to draw (because you know the prompts), but it's neeeeeever quite there.
Your images are awesome btw. Love the crystal balls and the bug... things?
