Reference: the image I uploaded is a rough pencil sketch of a logo idea, drawn on paper.

Task: develop it into 8 polished, professional versions of the logo:
1. Black line art, minimalist, on white.
2. Modern tech style with a blue-to-purple gradient.
3. Vintage badge with a subtle distressed texture.
4. Neon glow on a dark background.
5. Artistic watercolor take with soft edges.
6. A bold geometric take built from simplified shapes.
7. Embossed gold foil look on dark card stock.
8. Organic hand-lettered style with natural curves.

Rule: in every variation the core concept and the symbol stay recognizable, while each one takes a clearly distinct visual direction.

Layout: a 4×2 grid, every variation clearly separated from the others, with a small label under each one.
Output: high resolution, 4K, fit for showing to clients.
