Drupal 8 artist site frontpage and content display

I need a new frontpage for my drupal 8 site and content display improvement. - The idea for the frontpage is a big square slider (2/3 of the page) and different content around (check layout example), it is necessary to keep it simple, please send a mockup first - Every content should be displayed nicer than now by arranging title, image, various information - Add image galleries: from the main navigation link to different galleries - Every image should be able to be viewed bigger - Show a view with guestbook entries and a link to the form (guestbook module) - Update drupal 8 and modules to the latest version
