Can anyone recommend how to keep consistency across image generation and to follow the instructions given

I have been trying to generate martial arts moves and it starts out with the most amazing work but then it will change certain things but most importantly it will generate what I ask and have a jab and a cross with the same arm or a side mount will be a full mount. I’ve tried giving it references, tried changing prompts. Im running out of time and it’s so frustrating and depressing because the stuff it did create correctly was so much better than I ever could have imagined but now im about to have a heart attack. Any suggestions are greatly appreciated.
