Ooooooh. I dig this.
I tried something like this cdn.discordapp.com/attachments/575769965551026204/740634748405153802/Koi_pondering_alt.png maybe it's good enough to put it up on my store, also sorry for using a massive Discord link, I just use Discrod for quick image dumps.
I looove those "whoosh" lines - so crisp, and they add a lot to the composition here without being too obvious about it. I think the cool patterns in the background could probably spread out diagonally, dragging towards the opposite corner, so the piece doesn't look quite so obvious in its copy-flipping.
