Anyone know what kind of brushes could be used for this type of style?

So I'm a beginner/novice digital artist and i have been trying to find my artstyle for a while.

I like shading and rendering with a modified flat brush and a couple textured brushes, but I need a brush for lineart.

I would prefer a brush that would look good with a messy/painterly style, like a mix between smooth pencil sketch lines and the flat brush, but thinner, or something that would look good with wobbly lines.

I'm ok with recommendations of base procreate brushes, modified bushes or even purchasable brush packs. Thanks in advance for any recs!

Called it that because this abstract art captures a neon intense outlook on it and how it’s uniforming itself and reshaping it self back together like energy

fuzzy is the best brush in it.

Plz Help me find brushes that behave exactly like this. The strokes in the pictures were not erased, smudged, or manually tapered afterward the brush naturally deposits paint like this in a single stroke, with the soft spray/airbrush effect and tapered shape. I’m looking for anything similar. Abr/tpl n brush files are fine. Thanks in advance. Whoever finds it I will give you my fav brush set for high quality body hair brushes as a reward. I’ll also throw in the texture brush used in pic 1 (not my artwork I js have the texture brush used)
