Key differences between a girl thinking you're too hard to too easy to get

[demigod]

Hi guys,

I'm having trouble telling whether girls think I'm too hard or too easy to get. I'm leaning on too easy, but the reason for confusion is I generally act very cold/cool/aloof during interactions.
I do have a constant somewhat serious expression on my face by default, so I was wondering if that might be anything to do with it. I've also been told that I look judgemental...

I've lost a few girls before by being too distant and now when I'm trying to be warmer I'm not getting much different results.

What do you guys use as indicators?

Cheers
