New to Qwen Image Edit, it seems to fail a lot of commands, what am I doing wrong?

Hey guys! I've just discovered "edit" models, and it's. frankly, the HOLY GRAIL of image generation. Its consistency is just mind-blowing. That is, as long as I stick to clothes swap or environment changes. Trying ANYTHING ELSE, the generations are distorted, unrealistic, and inconsistent with the image inputs. Is there some weird secret to know about these models? Again, clothes swap gives PERFECT images, so my settings don't seem incorrect.
