Nano Banana 2.1 6 / 10 Ranks seventh as a competent, appealing illustration with all the basic subject elements. Its substantial stylistic departure and less precise gardening mechanics outweigh the attractive decorative detail.

Nano Banana 2.1 6 / 10 Ranked 9th because its polished execution is outweighed by a substantial stylistic mismatch. It could function as a dimensional weather badge, but it is not a strong modern flat-icon solution.

GPT Image 2.5 Flare 5 / 10 The action is recognizable, but the enlarged and stretched hand geometry significantly detracts from it. This is weaker than the leading outdoor images despite its clear composition.

GPT Image 2.5 Flare 9 / 10 Rank 1 of 13: this combines the strongest bifocal execution with excellent skin, material and lighting detail. Slightly over-crisp reflected scenery is the main obstacle to a flawless score.

GPT Image 2.5 Flare 4 / 10 The wrong sign combines with softer execution to limit this image's success. It ranks ninth because it retains an appreciative context but lacks both gesture accuracy and stronger photographic detail.

Nano Banana 2.1 8 / 10 Ranked 2nd of 13, this combines some of the best photographic realism with a substantially more relevant handshape and placement than most alternatives. Slight uncertainty about the exact signing position and the nonplain background keep it below the strongest match.
