I used Brush/Paint and selected the blue background color. I painted over the background to remove detail. This will help to simplify the results of the following “pixel” steps.

After applying the pixels step, I saved the image to my camera roll. Then with the image still open, I used Brush/Paint and selected the blue background color, and with a large brush, I painted over the entire image to make a solid color image. Then I used Effect/Blend to blend the previously saved image onto the solid blue image. I used my fingers to shrink the image and place it where I wanted it.

Still in Brush/Paint, I changed the settings to select a small brush size and setting the size variation to its maximum setting. I selected another color from the image, and painted a line.

I used Preset 8 in Effect/Pixels, and painted a brush mask over the upper part of the image, so that the pixels effect would apply only to the “garment.” After I applied the effect, I removed the brush mask. Then in Brush/Paint, I selected the blue background color and painted away some of the “garment.”

I used Style/Flat 2 Preset 3 at low opacity, and adjusted the Threshold and Radius settings. I selected a swatch to alter the colors.

I sometimes try blending an image with itself with a small rotation and/or offset. Here I used the Phoenix blending mode at medium opacity, and with a small rotation. I always try the BlendIf slider.

I used Style/Water to soften the image a bit. I used Preset 16 at low opacity.
