I couldn’t find any good wobbly brushes for krita, so I made one of my own. It’s inspired by yugo limbo’s lineart 
The ‘wobble’ effect is a little subdued, but you’re free to go in and tweak it, here’s a small sketch i made to preview the brush:
here’s the link to the brush! (its a bundle, but there’s only one brush in there)
This is my first brush in krita, let me know if anything is wrong and I’ll try my best to fix it.
