The beautiful texture for this image comes from Metabrush. The distortion is created in iColorama using a very simple image to distort the face over.
I started with this photo from Pixabay, a source of copyright-free images. I love the shape of her face, and the clean, simple lines.
In iColorama, I improved tone and color. To smooth the face and remove the freckles, I used Effect/Denoise with the Smooth preset once or twice at full opacity, then Style/Simplify preset 1, then Style/Coherence preset 1.
I created this version for another image I made, my method is here.
I painted the image in Metabrush. I used a variety of stipple brushes.
Then back in iColorama, I used Effect/Distort to distort the image over this pattern, which I created in iColorama.
Final image.
