AncestorCloud user authentication modal

Finally my first submission to dribbble! Hey everyone, make sure to follow for more user interface with product talk shots.

Last iteration over AncestorCloud's user authentication modal.
I decided to go with using tabs to make it as simple as possible for a first time user to have the sign up form front and center, yet still convenient enough for return users to find the login form.
