Amu, very nice drawings! Regarding the eyes on the side tilt, I think it may be an alignment issue. If I hold up a straight edge such as a pencil to the line of the lips and the line under the. nose and then carry up to the eyes, that is where I see the eyes are not in total alignment. For example, I think the indentation by the left eye may be too low and the left brow lower than the right. Try it and you might see what I mean.
