I found a brush on here I liked but can't find it anymore, so here's a remake and two variants.

All 3 brushes were used on this peach.

Top: Soft Flat Paint Brush - an easy to use solid paint brush. At smaller sizes, it's sharper for fine details.
Bottom: Roughly Paint Brush - good for hair & general painting, with a little texture for variation.

Roughly Textured Brush - a more intensely textured version of the brushes. Change the size of the texture & other options for different looks. I used this for the spots on the peach.
