Hey I am fairly new, but have been reading PUA guides for the last year now. I feel that I have a lot of it down. But I think a big problem I have lies within my face.

I tend to have a blank stare, I like to think of it as an Indian death stare *since I'm part Indian*. Its my default face that looks like I'm staring right through you, am uninterested, or pissed about something.

I am not an upset person, I just have trouble holding facial expressions for periods of time, and I fear that this could make people feel uneasy.

How important is facial expressions? Is there techniques or some form of practice that I should do?

Facial expression is important, you don't want to walk in looking like a goof or like your rdy to kill.
Only advise i can give you is to use a mirror, do what actors do to get that red carpet look and look at yourself in the mirror doing some expressions then go out and try to keep that expression throughout a conversation, yes it seems dumb/goofy/non-straight/whatever but it works and practice makes perfect.
