Have fun
I can’t find a creamy impasto brush like I wanted,

So I tried to make something similar to what I envisioned.
You can turn on/off the watercolor edge according to your tastes.
It helps the brushes to stand out and have this 3D feeling.
You can also change the brush tip angle to fit your preference more.
The sub color will show more dominantly, so choose the colors carefully.
