What is the best way to achieve the gradient effect in these photos?

Hi! I’m planning to do this photoshoot and then in post,edit these gradients in these segments. 

I was wondering what the best/ most effective way was to create the gradients for this look.

Thank you so much for your time

I would probably use a stipple type of brush in pixel persona in Designer or in Photo and paint the gradients on a layer above so it's non-destructive. Make sure the colour you paint is the same as the background and you'll get a nice gradient fade into the background on those shapes.

The middle image looks like a different process.

he made some selections where he mirrored the selected parts vertically and used the background color brush strokes to cover the edges resulting from the process.

I managed to come up with something interesting with only Adjustments and Live Filters.

It’s not quite what was wanted but it’s maybe a starting point – lots of tweaking needed for better results.

You could maybe add a mask over the whole lot and use that to remove the bits that aren’t needed.
