I think it looks good so far! I think you need to move the lips a bit higher up, since its too close to the chin.

Its really realistic from this point. You just need to add some shading.

Yeah. The face is slanted like this / a bit, but you could probably fix it. The right eye needs to be lower. The nose doesn't have these )( marks. The nose's holes need to be a bit more visible. Shoulders have to be a bit flatter and a bit rounder for the left one. Nose needs to extend a bit more. Eyebrows need to be less slanted. Inner eye corners less pointy. Skull bones near the cheeks don't need to be too visible. Face more symmetrical. If you're going to do shading, you should do some under the lips, chin, skull lines near the cheeks, forehead, near the nose, at the eyes, and directly under the face at the neck. Sorry for the ranttt.
