Ooooo-! That's looking noiceee-! 😯✨✨
You don't have to worry abt chin nor eye placement- since it's your preference on how you want them to look-
Also for neck- it's also technically your preference- but if you can't seem to find one- I suggest trying out different neck sizes and styles- that's what I technically did- and came up with kinda long necks with an Adam apple for males and a bit smaller then guys and no Adam apple for females-
But practice makes perfect- 😌✨
