Modern Poster Graphic Enhancement

I have an AI-generated poster that is almost there, but it still needs a professional touch. Using Adobe Photoshop, I want you to:

• Refine and balance the colors so they feel bold yet cohesive.
• Add subtle texture work that lifts flat areas without overpowering the design.
• Sharpen or redraw small details that currently look soft or rough from the AI render.

The overall look must stay firmly modern—clean lines, contemporary palette, no vintage filters or minimalist stripping back.

Please supply:
1. A layered PSD (so I can make future edits).
2. High-resolution, print-ready PDF in CMYK.
3. Optimized web version in RGB (PNG or JPEG).

I’ll review and request up to two quick adjustment rounds focused on color or texture tweaks only. If you’re confident with precise Photoshop retouching and have a keen eye for modern design aesthetics, I’d love to see your approach and timeline.
