Sleek Logo & Thumbnail Design and any design

I’m refreshing my brand identity and need a clean, modern logo paired with an eye-catching thumbnail that share the same visual DNA. The look should feel sleek—think balanced negative space, crisp lines, and typography that conveys confidence without clutter.

Key notes
• Style: Modern and sleek (please avoid ornate or dated treatments).
• Colour: I haven’t fixed a palette yet, so feel free to propose options—monochrome minimalism, muted neutrals, or a bold accent, as long as it supports the modern mood.
• Elements: I’m open to an icon, word-mark, or a smart combination of both; present what you feel works best for the concept. Creative rationale counts.
• Versatility matters: the logo should scale gracefully from social avatars to print, and the thumbnail must stand out at small sizes (e.g., 1280 × 720 for YouTube).

Deliverables
1. Three initial logo concepts with colour suggestions and mock-ups on light and dark backgrounds.
2. One thumbnail concept aligned with the selected logo direction.
3. Finalised assets:
– Vector files (.AI, .EPS, .PDF)
– Web-ready PNG/SVG with transparent backgrounds
– Thumbnail in high-res PNG/JPG
– Font names and colour codes (HEX/RGB/CMYK)
4. One revision round after concept selection to polish details.

Please share a quick note on your thought process, any relevant portfolio examples, and an estimated turnaround. Looking forward to seeing a concept that feels unmistakably modern and instantly recognisable.
