User-friendly form validation

I'm currently working on the app that has forms with lots of different fields.
So I've been working on a form validation mechanics that should help users to fill the forms, rather than bombarding error messages to their screens.

This shot above is what I came up with now.
It feels more like a tutorial with several steps, rather than a complex form submission.

Made with AngularJS and Bootstrap.
