Neutral Earthy Poster Revamp

I have an existing poster that already contains the right text and imagery, but it needs a fresh, more visually appealing treatment. My priority is refining the colours and contrast so the design feels cohesive and polished while staying true to a neutral, earthy palette—think warm tans, muted greens, subtle browns, and soft greys rather than bright or dark tones.

The layout can remain largely as is; what I’m after is a skilful eye to harmonise the colour scheme, balance tonal values, and ensure every element pops just enough without losing the understated feel. If you see small typography tweaks or minor graphic clean-ups that would amplify the overall look, feel free to propose them, but the core task centres on colour work.

Deliverable: a print-ready, high-resolution file (PDF preferred) plus the editable source file so I can make future updates if needed. Please keep all existing copy intact.

If you have experience elevating posters with nuanced colour grading or brand-aligned palettes, this should be a quick, focused project.
