Simple Logo Refinement

I'm looking for a talented designer to help refine a logo. I have an existing design that I'd like to use, but I need some professional tweaks.

Requirements:
- Add or remove shapes and lines as needed.
- Provide the final logo in both vector and raster formats.

Ideal Skills and Experience:
- Proficiency in vector and raster graphic design.
- Strong eye for professional logo refinement.
- Experience with client-provided designs is a plus.
