1. I generated the characters, and save them without background/frame.
2. Open Photosop, and the characters.
3. I copied the female character to male. (you can use the layers (f7).
4. i removed some part of the female, for more blend (he guarding she with a shield)
5. Optional, but i added some background.
little thing, but as you see the colours are more deep.
because i duplicated the layers, and set the new layer “soft light”
you can see the differences without and with soft light
