A login-in page could give a first impression of its application probably. As always, it is hard work to design on it, especially choosing an image or drawing illustrations for presenting the right impression and putting the layout efficiently.
I consider below for the right login page.
Focused: Login takes sole focus, with no additional details given to marketing or advertising.
Multi-Account: A focused login for a service that supports multiple accounts
Nested: Login takes focus, but it is framed within the marketing site.
Marketing-Forward: Login is often placed alongside the product marketing site.
Billboard: Login uses the page to advertise other services.
