I've created many interesting textures in Metabrush, using the method I describe here. For this image, I wanted a simple design that emphasizes the texture.
I started with this photo from Pixabay, a source of copyright-free images. I liked her serious gaze.
In iColorama, I used Form/Warp to change the shape of her face, and I applied Style/Flow preset 1 at low opacity to smooth the face. Then using Brush/Paint, I painted catchlights in the eyes.
I created this texture in MetaBrush. I used Brushes/Paint mode, using the Petro 1/13 brush at 100% opacity and medium size. In brush settings, I set spacing to its maximum value, I set position variance to its maximum value, I set rotation variance to a middle value, I left dynamics at their default values, and I set Structure and Noise to their maximum values and Shadow to a middle value. As brush image, I used a simple bluish white high-key photo.
In iColorama, using Effect/Blend, I blended the texture over the face. I tried several blending modes and slider settings. I used my fingers to size and position the texture image on the face for the best result.
Still in iColorama, using Brush/Paint, I used a hard square black brush to paint the background and get rid of her hair, to simplify the image.
Using Effect/Blend and an inverted brush mask, I blended in the eyes and mouth from another finished image.
This is the image I used for the eyes and mouth. You can see how I made it here.
I used the Elasticam app to fix the size and shape of the eyes and mouth, and to change the shape of the face. Then I opened the image in iColorama and used Form/Crop to crop it.
In iColorama, I used Tone/Enhance and Tone/Pastel for tone and color adjustments, and I used Effect/Raise to emphasize the texture. I added a border using Preset/Border with a brush mask to allow the figure to extend across the border.
