Krea2: Use 'WLOP_Style' (You may try without a trigger word, on landscaped images it will often add a caption to the image. This is particularly important with other LORA models or non-vanilla model.), 'Digital painting of' or 'painting of'. For single lora use strengths 0.9–1. With lora of character (especially highly realistic ones) use a strength of 1.3 or higher.

Z-image turbo: Use "WLOP_Style" and "Digital oil painting" as triggers; strength 0.8–1.0. If you are using character LORA, use strength around 1.1–1.2, depending on that LORA. Be careful when using ADetailer, especially on faces: the Lora intends to add sparkles to them. I recommend setting denoise in ADetailer no higher than 0.35

Used WLOP's images until 2021. After that, in my opinion, he started using too much 3D and the new images lost much of their atmosphere.
