From what I see:
The hair,boobs either have no bones or need to be animated with jigglebones or manually.
The right hand doesn't stroke straight, instead goes up and down, but the dick is stationary. Not sure if it's a wall ornament like the one behind, but just make sure the hand goes straight.
The eye does some weird white shit.
The neck area needs some movement to look realistic.
It also looks like there's some needle at the point of the dick so that she immediately backs away when she's sucking. lol. Not sure if intended.
That's pretty good for a first one, better than mine. ^_^
