Hi Anubhav! I can’t find a place to reply to your request for help, so I’m posting here. Your drawing of that beautiful girl is great. The style reminds me of a Matisse portrait with a splash of Picasso!😂. It reflects all the hard work you have put into it. I’m so sorry your client didn’t appreciate it. They obviously want something more realistic. Since it is a blurry value only photo I think you really need to darken the darks and slightly lighten the lights in her skin. Darken the eyes and mouth. I added some darks to the left of her face and added some lights to the right. She needed to loose a bead from her necklace under her neck. This changes the placement of her neckline. I think that solves the reason her head appeared tilted. Hope this helps.
