feels like almost no impact, try pushing the pose out of the safe one you seem to be using for the whole duration(the top of the thigh should be much bigger close to camera, drop her head too). Really bend her, and don't jiggle the butt at the glass. If the skin's pressed then it aint moving. Also I have no idea what those arms or doing or why. Are they supposed to be pushing into the thighs to add to the action? If so it doesn't even look like they touch. Cute character and nice hair flip though.
*edit* i can't help it if you read it like it's an attack. it's all just suggestions
*another edit i guess* yep, that's a question, followed by a suggestion based on what i thought your response may be.
