She likes to fuck!

If you're the creator, you might want to work on the facial expressions. Her eyes especially seem very expressionless. Stoic and almost the same in every pic. Makes it unnatural looking and feel kinda dead. Like a mask.
The mouth is a bit better, but it's still quite unmoving except for the BJ.
I normally don't suggest to get sexual information out of porn, but if you find one where the female's face has a lot of screentime, you might want to look at how their expressions change and try to emulate those in your pics.

Thank you again!
