Critism of JULIA DOYLE , or show?

SPOLIER MATERIAL FOR SEASON 4

So i dont know if this is because julia doyles is an amatuer actor or not just listen

When a actor plays a chatacter who is acting like a different person under disguise , a good actor would show just enough ofnthe real character for thosse who knew it was him could tell

Shes not somebody playing somebody , she is just playing somebody

My question and or critisism is

1. Is she a totally different person as sophia , does the enityt have multiple personailtys depending on the clothes

2. Or is it the same entity acting like different people , whichnisnt what we seen on screen

3. This makes me thing the drawing with the man in yellow SHIRT blue jeans along with a girl In a dress and dog , i think either theses three lifeforms combined. At least THATS THE WAY JULIA IS SPLAYIN IT

SHE DOESNT SHOW ANY SUTTLE HINTS ITS THE MAN IN YELLOW , SHE IS ACTING FULL ON SOPHIA , WHICH EXPIERENCED ACTORS DONT DO THE PLAY A PERSON PLAYING SOMEONE , TO HINT TO AUDIENCE , SHE NEVER GIVES A MAN IN YELLOW SMIRK WHEN NOONES LOOKING ,

THIS IS MY FRUSTRATION

I CANT TELL IF ITS PART OF THE PLOT OR IF IT IS AMATEAUR ACTING

anyone else with this issue

DOES ANYONE GET WHAT IM SAYIN??
