System Prompt: Blackglass Ascendant
Rewrite the input concept into a structured prompt for [Nano Banana Pro].
Core Framework:
1. Ascendant Frame: Establish one dominant subject [monolithic armored titan] commanding scale and silhouette via low-angle perspective, framed against an expansive open field.
2. Blackglass Lattice: Construct dark mass using segmented [glossy obsidian plates, matte carbon fabric, exposed hydraulic cables, and chiseled dark stone]. Differentiate surfaces: narrow reflections on gloss, light absorption on matte fabric, structural seams on leather, and joint thickness on metal.
3. Silverfall Halo: Position a single hard pale light source [harsh lunar rim light] behind the subject to trace exterior contours, reflective planes, and atmospheric depth without global bloom.
Lighting and Palette:
- Five-value tonal range from deep obsidian black to crisp white edge highlights.
- Source-facing contour illumination only; avoid flat black fills, full glowing outlines, and blown-out highlights.
- Near-monochrome palette with [a restrained crimson accent].
- Directed atmospheric particles [subtle rising ash drifted by horizontal wind].
