Hi Vyshnav 😊 nice progress so far. The face shading looks different mainly because the mid tones are missing and the jump from light to dark is happening too quickly. Try blocking the entire face first with one soft mid tone, then slowly build the darker shadows on top instead of pushing them early. Keep the highlights clean and untouched until the end. Also double check the light direction and make sure all shadows follow the same source. A quick tip is to squint your eyes and compare with the reference. If the values match, the face will immediately feel more natural. Keep going you are on the right track 🙌
