Animal Head Redraw Image Fix

I have a machine-generated illustration (PNG, 1536 × 1024 px) that needs a small but important touch-up: the animal’s head has odd artifacts and must be redrawn so it looks natural and consistent with the rest of the scene. No other elements require changes, and the overall colours, lighting and composition should stay exactly as they are.

Please work directly on the original-resolution file I’ll provide and return:
• a corrected PNG
• a matching high-quality JPG
both at the same 1536 × 1024 px size.

Feel free to use Photoshop, Krita, Procreate or any digital painting tool you prefer—as long as the final head blends seamlessly with the body and there’s no visible retouching line.
