Sliding Menu Animation

Another shot from a web app I'm working on for My SEO Tool I recently revisited the user menu as I had it as a drop down but I didn't like how it looked when it covered the 3 buttons below so I came up with this concept, don't mind the poor animation, the real coded version will be a lot smoother.

Let me know your thoughts. Make sure you view the @2x.

Attached are the static views. Menu Open | Menu Closed
