I'm not a big fan of the outline you used to indicate the next action. When I saw your tutorial, I couldn't see where the Login button is because of the thick orange outline hovering the login button making it hard to the "login" button. It needs to be outside of the labels and it should be easier to see.

You should research for a different way to direct users there, the outline should be optional. Maybe an arrow or other type of animation.

Other than that, it looks great and I can't wait to see it mature. I'd love to use it!
