80s 
Create an intentionally awkward 1980s double-exposure studio portrait of the person in the reference photo. Place the same person seated in a cream sweater in the lower-left foreground and a larger softly translucent side-profile of their own face in the upper-right background. Use a deep blue starry studio backdrop, soft airbrushed light and subtle film grain. Both faces must be clearly the same person; add no other people. Preserve every person’s recognizable facial features, skin tone, age, body proportions and expression. Do not beautify, replace, add, remove or merge people. Keep natural skin texture. Make only the styling changes explicitly requested by the selected preset. No added text, logos or watermarks. The second translucent profile is a deliberate repeat of the same person, not another person. Preserve the original expression and facial proportions in both views.

Use a front-facing portrait of one person, without sunglasses. The model creates a second view of the same person. Avoid group photos for this preset.
Leave room for the profile
Portrait 2:3 leaves space for the floating head above the shoulders. Keep the background simple and ask for soft transparency so the faces do not collide.
Make the joke work
Choose a serious expression, a plain knit sweater and a starry blue backdrop. Check that both faces resemble the source and that the smaller portrait has natural hands.
