Hyper-realistic macro photography of a human iris, warm amber and honey-brown color tone. The iris texture must be extremely fine, wet, and glassy, showing delicate, sharp radial fibers instead of coarse textures. On the upper-left side (between 10 o'clock and 11 o'clock position), there are exactly two distinct, organic dark brown pigment freckles.
