I've made a simple test to check the prompt fidelity and realism of all the models i have, with a simple and yet not so mainstream prompt. See attached files for full resolution images
Let me know if you find it useful but, above all, drop a lot of criticism down in the comments <3
As you can see, many models mix the green of the eyes with other elements: almost every model puts leaves in the image, and many of them create an unrequested reptile skin with its unfitting requested human eye; many models also create unrealistic iris.
Here i've made a personal selection of the models that created the most realistic result, even if not strictly adherent to the prompt (like the anime girl viewed from too far):
(the first half of the last column is repeated in the second half of the first column because of laziness, sorry about it)
Here are the generation data:
