I’m adding pics so you can see the differences.
If we look at female blush animations, we can see they all look different.
While male animations flirt_shy and talk_greet_shy are completely the same, with one difference- talk_greet_shy opens mouth to talk.
Flirt_shy animation doesn’t look like flirting at all. Flirt_shy should be renamed to greet_shy.
Maybe this pic is more like flirt shy:
If you have a better example of male flirting shy, please add it to your comment.
And click LIKE if you agree.
