Professional Logo Touch-Up Needed

I have an almost finished logo that needs a touch up to correct the shape and quality.

Deliverables
1. Versions (each in full-colour gradient, plus single-colour white and single-colour black):
- Main logo (symbol)
- Small-size symbol
- Sticker edition
- Wordmark on its own
- Horizontal lockup (symbol + wordmark)
- Stacked lockup (symbol + wordmark)
2. Source files: fully layered, editable Adobe Illustrator (.ai), no embedded images, plus a version with text outlined. Every element of the logo must be built in this file.
3. Vector exports: SVG (optimised for web), PDF and EPS, for every version.
4. PNG exports (transparent background) at 512, 1024, 2048 and 4096 px, for every version.
5. Website and app icons:
- favicon.ico (16/32/48) and an SVG favicon
- PNG at 16, 32, 48, 96, 180 (Apple touch icon), 192 and 512 px
- a 512 px "maskable" app icon
- Open Graph / link-preview image (1200×630)
- email header logo (600 px wide plus a 1200 px @2x version)
6. Social media:
- Avatar versions (logo safe inside a circle crop) at 1024×1024, plus exports at 400×400 (X), 512×512 (Discord, Telegram), 256×256 (Reddit), 184×184 (Steam) and 800×800 (YouTube)
- Simple banners (logo on the brand background): X 1500×500, Discord 960×540, Reddit 1920×384, YouTube 2560×1440
7. Print and marketing:
- Print-ready PDF in CMYK, with the CMYK and closest Pantone values for the brand colours
- Sticker print file with the die-cut line (for vinyl stickers)
8. Mini brand guide (1–2 page PDF): clear space, minimum sizes, colour values (HEX/RGB/CMYK), and correct and incorrect usage.

Requirements
- The logo must be 100% original and built by hand by you in vector software.
- NOT accepted: AI image generators, AI or automatic vectorising (e.g. Image Trace), stock elements or templates. We will review the source files.
- Fonts must be licensed for commercial use (free OFL fonts like Google Fonts are fine). Please tell us which fonts you used.
- All copyright and intellectual property in the final logo and all files transfer in full to me on payment, confirmed in a short written assignment. The design is exclusive to us and may not be reused or resold. You may not show it in your portfolio.
