A two-panel technical blueprint diagram

A two-panel technical blueprint diagram in clean monochrome line-art, matching the exact layout of the provided PlayStation 1 schematic. On the left side, draw a full, intact Sony PlayStation 5 console in precise thin line-art on a white background. On the right side, draw a highly detailed, vertically exploded-view diagram of the PS5 showing each internal component separated into layers: outer shell panels, faceplates, cooling fan, heatsink tower, Blu-ray drive, motherboard, SSD module, power supply, internal frame, ports, vents, base stand, screws. Use consistent thin grey line-weight with no shading. Add numbered circular labels around each part, and include a matching numbered parts list at the bottom just like the reference blueprint. Place the SONY logo, PlayStation logo, and “PlayStation 5” text in the top left in the exact same position and style as the uploaded reference image. The entire artwork should mirror the composition, spacing, typography, and minimalist engineering-manual aesthetic of the reference diagram.

A hyper-realistic, high-resolution portrait infographic

A hyper-realistic, high-resolution portrait infographic based on (your photo). Keep the same person, identity, hairstyle, clothing and natural skin tone from (your photo), with a neutral studio background.Overlay a subtle, semi-transparent facial analysis grid on the entire face, very similar to a 3D face-scanning mesh: thin, soft white lines following the facial contours, slightly glowing but not hiding the skin details. Add one clean vertical red laser line running down one side of the face, like a futuristic scan. All analysis lines must be soft, minimal and elegant, exactly like a cosmetic-tech advertisement.Create a clean medical–aesthetic infographic that evaluates 5 aging factors using global data percentages:1. Fine lines and wrinkles2. Skin texture and elasticity3. Facial volume and sagging4. Eye area aging signs5. Skin tone and pigmentationFor each factor, place a small label with a thin line pointing to the relevant facial area, and next to it write a short title and a realistic percentage score from 0–100% (based on global data), for example:“Fine lines & wrinkles – 18%”“Skin texture & elasticity – 72%”“Facial volume & sagging – 35%”“Eye area aging signs – 41%”“Skin tone & pigmentation – 63%”Use clean, modern, sans-serif typography and small technical-style text, like a scientific facial analysis UI. At the bottom of the image, in the center, write a large bold text showing the final estimated real age based on the analysis, for example:“ESTIMATED AGE: (random number based on face analysis ) ”Overall style: futuristic AI-guided skincare analysis, minimalistic, premium editorial lighting, no gender mentioned, suitable for any human face.
