Do you mean a list of adjectives to describe facial expressions?

Some positive words..... sympathetic, kind, friendly, empathetic, open, cheerful, joyous, warm, passionate, sincere, trustworthy

Some negative words..... scornful, sarcastic, vicious, grumpy, embittered, sulky, insincere, devious, stubborn, untrustworthy

@Kate,

A ¨poker face¨ is a way to describe someone with the ability to keep from giving away what they are feeling by their non-verbal expression.  In poker, it is useful to dissimulate and a ¨poker face¨ is part of this. The best poker players have to be able to hide their true feelings and ¨bluff.¨   

Or she has surly face means she's unfriendly

but I don't agree with this ,actions clearfiy the real feelings
