GROK IS GOOD!....When prompted correctly....and when it works
But even when the prompt is good we will have to try 2 or 3 times before we get good results. Fortunately the daily usage limit for free Grok is big (Dont know the exact number)
Prompt I Used: Lock uploaded image as base frame: woman centered, long hair visible. Man enters from the left and stands beside her. He pulls her long hair and pushes it inside the boxers he is wearing. Fabric settles naturally
