great to see you working in here mona. the start looks great.
about the mouth, yeah it actually looks like its a bit low in the position wich could come from the looking down. also, the distance usually is a bit bigger there if somene has a button nose 
highlighting on the lips/chin-area in the right softness and mass definition probably clear the angle
(had to fight with the same in my desire piece) looking forward to your next update
keep up the great work Mona 

Only kidding you…I really think you’d do a lovely set of natural images, like the early naturalistic work of illustrator
don´t you see it? L


hehe
