Hello @dialanche, and welcome to the forum!
I guess that you can do the oil-painting impression with the brush-set from @emilm, the distortion can be done with the brushes Krita ships with:
But I think also the “Daishishi Thick Oils”-bundle from @Daishishi is worth to try for this kind of painting, but there exists only a Google Drive download-link, at least as far as I know:
And this older and experimental bundle from iForce73 obtainable on DeviantArt (where you need to register to be able to download) may be worth a look, too:

And because @raghukamath posted additional info in between, I don’t need to further explain the way you can achieve it.
