it doesn't contain any prompt data but they look similar to dreamshaper

I suggest asking the creator of these images directly

I think there are models that fit better. Propably it is  guofeng, xxmix9realistic or something from leosamsMoonfilm. If you us one of them to create similar images, effect should be almost the same as on your photos.

One things i can say, for the ''Character's'' He used perhaps my Lora of Noshiro: https://civitai.com/models/25394/noshiro-azur-lane-lora, For the model's not sure. Probably somethings Like: DreamShaper/RevAnimated/MajicMix atleast you can obtain these result with these model's.
