Tell me how you position your drawing pad and your reference photo. Do you use an easel, table, photo stand, or what? How big is this drawing?
The reason I ask, it appears that you have some distortion, as if your pad were laying on a flat table, and you were drawing as if you were writing. You see, the mouth and nose appear to be out of alignment, as well as the eyes and nose. They appear to be obliquely elongated to the right as you proceed upward. The viewer's right cheek looks too far right, the nose to the right of the mouth, and the eyes to the right of the nose. Follow?
This can happen when you place the reference photo to the side, or if you draw on a flat table with the pad rotated left as if you were writing.
Also, the ear seems a bit small.
I recommend a drawing table which is about at a 45 degree angle, and the surface of the pad at its center perpendicular to the line of vision. The reference photo directly in front to avoid distortion.
Clearing up these environmental issues can save an artist some grief.
