Replace “Change the color palette to sage green and warm ivory, with gentle pastel gradients on the body” with “body primarily sage green, warm ivory muzzle and belly, clearly separated opaque color blocks, minimal white.” You can also replace “cool light-gray studio background” with “deep muted sage-gray studio background” to reduce the image’s overall white balance and strengthen the hippo’s color contrast.

Replace “front-facing seated pose” with “tight front-facing portrait crop from the chest upward, face filling most of the frame,” and replace “Centered composition” with “centered close-up with oversized snout as the dominant foreground feature.” Keep “small dark pupils” and “tiny ears,” but add “sharpest detail on the eyes and snout, gently softened body edges” to shift attention forward.

Keep the load-bearing identity phrases “cute minimalist baby hippo toy,” “soft rounded forms,” “tiny ears,” “small dark pupils,” and “oversized snout” unchanged. Swap only the palette and setting, such as replacing “sage green and warm ivory” with “powder blue and butter yellow,” or replacing “cool light-gray studio background” with “warm cream studio background with a faint vignette,” while retaining “centered product-style composition” and “soft diffused studio lighting” across every image.
