Everyone knows what it's about. Better stability with the poses, better perspective, better depth of field, etc. It will depend on the model you use and its training.

Trigger: Against the Glass

The best thing is that you can remove the characteristic frame of a window or shower, something that is usually tedious in models who are not well trained in this type of poses. Just add to your NG prompt:

frame, edges, border, corners

But! for obvious reasons you must use it without the following prompts or it will generate elements in the foreground to create an image with depth of field:

(depth of field:1.5), blurry edges, high angle
