Well, right off the bat I see you are going to have trouble modeling the sternomastoid muscle
because you don’t have a line of faces following this beige line
In addition, you need to bring in some of those edges closer to the corner of the mouth so you can make the nasolabilial fold (rust colored line)
One edge loop in the crease, one on the ridge, and a second pair of crease and ridge if you want to put in that dimple. You have the edges, they are just in the wrong place.
