There's a garden in the town I'm currently sequestered that has a centrepiece mosaic like this.
But it's surrounded by gravel, not flagstones.
I could simply photo this and mess with it to make my own texture maps for a dds - if you don't have the software to do that, there's plenty available to buy or, if you drop me a message: I'll lend you my copy of Bitmap2Material to use.
It also looks like a decorative manhole, of which there are many examples.
- One good way to capture texture relief for things like manholes or carvings, is to get some washable ink and use a roller to coat the thing.
- Then use some paper to lift the texture from it, washing the ink away so you're not vandalising anything, like lifting fingerprints using dust and tape,
- This will give you some solid outlines that can be simply auto-traced into vector after scanning, or scanned and, using a threshold filter to remove all the white for transparency, saved as a .png (or .gif, jpg's don't have transparency).
This is the same process as isolating tyre/shoe treads/splatter-patterns from a photo for forensics.
- Then make a rubbing (put paper over it and go over it with pencil, like at primary school), so you capture some details or if you want a negative relief to overlay on your positive relief, using a layer-style such as exclusion or screen (if you invert the colours at around 30% opacity and 30-50% fill).
It looks like something from Cthulhu:

Or from Ancient Greece:

Or find a free-to-use octopus-like mosaic from the internet:

What I would do is either buy that patch (or nick the image - or draw it) or trawl ceramic squids and octopus mosaics, photograph/scan it a few angles / run the image(s) through Photoshop / GIMP - probably the old "sponge/mosaic" art filter to make the "pebble" and another layer with "find edges" overlayed to distinguish them
Perhaps I'd use Adobe Illustrator / Inkscape to draw extra stones because it's easier than drawing paths in PS, as it's a pretty simple bunch of shapes, and then chuck that into PS (vector paths only) to give each shape a different part of a stone texture (if I didn't have one already, or didn't want to go outside to photo some, I'd get some from a place such as
https://www.textures.com/ and use them, overlaying this layer on the central motif and creating my basic image.
Then, I'd put it through Bitmap2Material, that will allow me to tweak and create all the different maps I need in order to output a 512x512 dds for use on a primative mesh, flat plane.
If it wasn't quite right - I'd use the B2M outputs to tweak the texture in PS/GIMP again, before giving it another shot.
This way - even if I can't draw - my theft is disguised because no-one will recognise the original image (unless I drew it myself with some pens, perhaps using my monitor as a lightbox so I can trace it, and scanned it).
Einstein said, "genius is nothing more than hiding your inspiriation", or something.
Would probably take an hour or so on the machine to get it how you like. Maybe an outing to find the source material to use, if you don't already have it stashed away some place.
I use black and white 35mm film, with a digital colour secondary, for my textures, because I can develop the negatives and scan them at a very high dpi, it adds a unique touch to everything and I can colour it how I like - but a camera phone does the job equally as well by itself.
Every photograph has some value to it, whether it be for textures or for reference for any level design/puzzle ideas - or for futhering another piece of work. This is why I have a few TB of images that I've organised and have forgotten about, so everything's in folders according to what's in the image. Might have a bunch of duplicates, but I know that I have at least something suitable that no-one else has ever seen before and I don't have to pay for or ask someone to get for me.
I'm sure you could do this, as you've managed to follow a tutorial to do the synthwave 80s' chroming thing on your picture - I've made them a lot for FCR and some indie bands, but rather than use the computer to make the chrome, I've developed a method using a thick stencil, a warm water bath and some Gallium metal to form the words, so that no-one will recognise the typeface (because I made it) and it's outstanding from the rest because it's not the same tutorial piled on top of all the other free fonts with levels/gradient overlays and highlights, that we learned to draw in workshop class at the age of 14.
Since it's unlikely that someone's going to say, "yes, here's a texture for you" - there's a method to make one, plus I'll post a few pictures to demonstrate how taking photographs of anything interesting is very useful and making day-trips to gather reference images and textures is not only fun but an important part of the job.
