I like using Metabrush for making big ropy strokes with interesting brush shapes. One use for such a thing is to make cartoon big hair, as I show how to do here.
I started with this image, which I made previously in iColorama. You can see how I made it here.
I painted over the girl in the Metabrush app.
Then I painted this hair on another layer in Metabrush. I had the hair on one layer, and different versions of the girl's face on different layers. I used Paint mode for the hair, using the first Kanji brush. In the brush settings, I rotated the brush to get the broadest stroke, with no rotation variance. There is size variance, so the hairs get fatter as you stroke. I used a large brush with not quite full opacity. There is spacing, which you can see in the brush strokes. There is some shadow and/or structure too.
I used this Rijksmuseum image for the brush image in the Metabrush brush, above. The Rijksmuseum website provides high-resolution images free to use and modify for any purpose, in their Rijksstudio.
Here, in Metabrush, I switched to a layer containing a different version of the girl's face, and I slightly reduced the opacity of the layer containing the hair.
Here, in Metabrush, on another layer, I painted over the hair using Texture 2 mode and a different brush tip and brush settings.
In each menu of the brush settings, I had all the sliders set to zero, except the two shown here at 50%.
In iColorama, using Effect/Blend, I blended the two above images together.
I made some adjustments to color and contrast. I used Effect/Scrape at medium opacity for a more smeary look, and I used Effect/Denoise preset 2 to smooth in preparation for Raise.
I used Raise 1. In Preset/Border, I used preset 3 with the switch turned to White, at a small radius, to get a fade at the edges of the canvas. This is Version 1.
For a second version, I created this on a new layer in Metabrush using the Stipple 4 brush.
In iColorama, I blended her with the starting image. I made color, contrast and vibrancy adjustments, and I used Effect/Raise preset 1.
Using Adjust/Exposure, I darkened the background, using a brush mask over the face so it would not be darkened.
With the brush mask still in place, I applied Style/Lighten, which added some wispy white threads in the background areas.
Nowin Effect/Blend, I blended Version 1 onto this, using the gray slider under Set to control where the top image was blended (I didn't want to blend the face). (Alternatively, if you can't get what you want from the gray slider, you can use a brush mask). I used the Lightness slider under Set to darken the hair. Then I made some final contrast adjustments in Adjust/Levels.
