I have wanted to edit the size of certain figures in a generated image I have had three attempt asking for different sizes but it has not been successful The figures have remained the same size have remained

I described an Ig=mage that I wanted  to generate . The image was great and I wanted to add two scuba divers that were the same scale as the other figures in the image as if they were actually y part of it. I tried three times with out success  This was my last instruction and I attach the image. “add two scuba divers one with a lamp and the other with the a camera they should both be swimming around the deck of the wreck and be of a similar size of the other human figure around the deck make sure there is a small stream of bubbles coming for the breathing regulators  of each diver. make them seem part of the image not just stuck on as an after thought. The divers are still too big half the size should be good. The scuba divers look good but are still much too big in relation to the other figures and should be more involved with the ship wreck.”  https://firefly.adobe.com/generate/image?trackingid=BJ4T364Q&ff_channel=adobe_apps&ff_source=Creative+Cloud+Desktop&ff_campaign=CCD_blade&ff_content=card1_t2i&ff_audience=CCE&ff_campclass=brand&ff_camptype=app&product=Creative+Cloud+Desktop&product-version=6.8.1.856&view=edit&mv=in-product&mv2=accc&mv=product&mv2=accc&mv=product&mv2=accc
