Ultra realistic portrait

Same person as the reference image, same identity, I'm sitting on a royal sofa, smiling while looking at the camera, a book named "ghalib " in my hand, I'm wearing a white off coloured Anarkali with golden embroidery on it, dupatta is half on my knees, my skin appears flawless illuminating my skin under the camera flash, picture took by iPhone natural camera, the photo should have a grainy 90s aesthetic,, full anarkali should be visible, my legs are folded while I'm keeping my one hand on my knees and my palm is under my chin as if holding my face, smiling while looking at the camera, keep my face unchanged and make it look realistic.
