Refine Existing Indie Game Logo

I already have a finished logo layout for my indie game; what I need now is a meticulous graphic-design pass that brings every color and detail back in line with the original master character artwork.

Here is the scope in plain language:
• Match the puppy’s face size to the proportion shown in that same master art—nothing larger or smaller.
• Leave all outlines, proportions, typography, and the overall composition untouched; this is refinement, not a redesign.
• Preserve the clean, flat cartoon illustration style throughout.

Deliverables I will need at hand-off:
1. A high-resolution, transparent-background PNG ready for store pages and social media.
2. Fully editable vector files (AI and SVG) retaining all layers, paths, and color data.

Flawless color matching, precision alignment, and an eye for character consistency are critical, so please be comfortable working in Illustrator or other industry-standard vector software.
