Realistic Nature Scene Illustration

I need a high-resolution, realistic illustration that captures a full outdoor scene rich with natural details—think lush trees, varied foliage, interesting light and shadows, perhaps a riverbed or distant mountains if it serves the composition. No characters or architecture are required; the focus is entirely on nature’s textures, colours, and atmosphere.

The final artwork should be suitable for print at poster size, delivered as layered PSD or high-quality TIFF so minor colour tweaks can be handled later. If you work in Procreate or Clip Studio Paint that’s fine as long as I receive an export with editable layers.

Please base your quote on creating one finished scene, including an early sketch for layout approval and one revision round after colouring.
