Go toEdit stack, openView edits, tap on the last layer, i.e.Curves, and select theStack brush.
Selectively paint over the background area you want to remove with the brush strength set to100.

You have successfully created a dual tone effect for your portrait using Snapseed.
The most prominently used features in this method are Curves and Double Exposure.
you could learn more about these tools in ourSnapseed double exposure guide.
The only limitation with using Snapseed for creating a dual tone effect is less control over masking.
Using the Stack brush to mask your edits works fine.
However, it does not give you complete control over painting selectively according to the natural light source.
It seems like a lot of steps, but it’s quicker and easier than you think.
