Once I had my portrait open in Paintstorm, I made several duplicate layers. I turned off visibility for all of the layers except one. On that layer, I used the selection tool with the circle selected. This way my selections would be curved. I made a selection that was a very large oval that extended off the page. Then I lifted my Apple Pencil and moved the selection so that the lower curve of the selection was where I wanted to make my first slice. Moving the selection resulted in the vertical edge that you see on the left side of the selection, but that will still work. If you don’t like your selection, just touch Disable Selection in the Selection menu and try again. One you’re happy with your selection, choose Invert Selection in the Selection menu, and then use Edit>Cut. This will give you the result shown here.

Continue the process on the next layer (remember to first turn on its visibility). You can use what you did on the first layer as a guide for where to make the lower slice on the second layer. It’s okay if the cut doesn’t exactly match what you did on the first layer. Continue until you have the sections you want, each on its own layer. Here I show the sections I made, after using the Move tool on each layer to move each section around to create some separation between them. I also made a new layer below all the other layers and filled it with a color.

I tried several rearrangements of the sections. Here is an example. Notice that I decided not to use the top piece that had her hair on it. I did this to simplify the composition as well as to fit all the pieces on the page.

I decided on this composition. I like how the chin piece looks like it sort of fell off the face. I also like how the rest of the pieces keep an overall face shape, with the forehead piece looking like it’s cracking open the top of her head. Allowing some of the pieces to overlap helped me to keep an overall face shape and to fit all the pieces on the page.

I used the airbrush to paint in soft shadows where one piece overlapped another. First, I created a new layer above the layer with each “behind“ piece. I painted a shadow onto each of these new layers, near where the pieces overlap. I used the Eraser tool to erase any airbrushed color that strayed too far. For color, I selected one of the face tones, and I moved it to a slightly darker and slightly more saturated version of that tone. I changed the blending modes of each of the airbrushed shadow layers to Multiply and reduced their opacities as needed.

On a new layer just above the background layer, I painted with some roller brushes and the block brush to make a background with slightly more of a painted feel. I varied the color very slightly a few times as I painted. I tried the brushes first to make sure they would do what I wanted. When I was done, I saved the png image to my camera roll. I also saved a psd output file to iCloud so I would have a version with all the layers, in case I wanted to rework it at some future time.

I used the last preset under Style/Water at low opacity and with distortion set to zero and texture reduced by half. This has the effect of softening the image and muting the colors as well as introducing some texture and tonal variation. Then I used Adjust/Levels to bring back contrast (sometimes I try the presets under Adjust/Shadows for this). Then I used Adjust/Exposure with an inverted brush mask to lighten the eyes, which had become too dark as a result of the previous steps.

I used the first preset under Texture/Leak, and I used my fingers to stretch and position the effect to get mainly the yellow and orange parts of the effect, and I chose Soft Light as the blending mode. Under Set, I used the saturation slider to tone down the color a bit.

I used the Shadow slider in one of the presets under Adjust/Shadows to increase color and contrast, then I used Effect/Sharpen to sharpen the image.
