Gritty Elephant on Orange

Create a minimalist, hand-drawn illustration on a solid orange background. The central image should be an ancient elephant. The style should be gritty, sketch-like, with clean blue tones and a vintage poster aesthetic. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
