Convert PNG Logo to SVG

I already have two logos in PNG format and need it rebuilt as a clean, fully-scaleable SVG. During the conversion I’d like a couple of subtle tweaks: refine the overall proportions so the shape feels more balanced, and either add or drop a small element if it helps the final composition. Everything else about the mark—its concept, typography and recognisability—should stay intact.

You may work in Illustrator, Inkscape or any other vector software so long as the final file is a pure-path SVG that opens correctly across browsers and common design tools.

Deliverables
• Editable, layered SVG with tidy paths and no raster artefacts
• One high-resolution PNG preview for quick reference

I’ll review the first draft and provide quick feedback; a round or two of minor revisions is expected so we can lock in the exact proportions and tiny element changes.
