On my Android mobile the error response label is hidden below the keyboard. So on the first step if I type "test@test.com" and click "Continue" the error of "already taken" is hidden below the fold by the keyboard and the impression I got as a user was that the "Continue" button was broken until I hid my keyboard.
I didn't bother testing other parts but they could probably highlight or border fields with errors in red. Maybe put the response above the field. Just my 2 cents.
I intentionally tested an error path because in my experience that's what separates the joes from the pros in UX.
