So interestingly, one distinguishing difference between oil paintings and acrylic paintings is that the former has more translucency, whereas the latter can be more easily layered on in a way that covers up the lower layers. This is what, according to one of my mentors in art school who…

Creating a 3d scene and then using a light source could produce some interesting effects for sure. Since the layers are already in place, it's just a matter of setting up the scene.

And I haven't thought about making SVGs, but that's a really clever idea. I'm gonna add an issue to try this out.

Oh, and thanks for the heads up regarding readbility. I'll update the theme to account for that.

I am very much looking forward to see the results of trying it out, regardless of whether it works in practice! (negative results are also educational after all)

And thank you for looking into the accessibility issue regarding links!

It was more of a stylistic choice on my part. I could add more layers to flesh out background details. And it's Hong Kong actually. :)

I think my main issue with it is that you don't end up with the impression of brush strokes on those areas - in a painting even big flat areas of colour tend to have clear evidence of brush strokes

That's because Gaussian splats are ellipses without any texture of their own (more or less), missing any detail that an actual brush stroke would have. Because the ellipses are so elongated in the finer details it feels like layered brush-strokes, but in the coarse background the "flatness" of the splats dominates. Compare to my stippling notebook[0], an even more simplified image filter (it's "just" tiled circles) with a similar "problem". Turn on the fake vignetting or tilt-shifting, and really turn it up for a similar effect.

If the goal is to create a paintlery illusion then there are undoubtedly ways to mitigate this lack of texture though.

Indeed, with these kinds of things it's the journey that counts. And no problem, thanks for letting me know.
