We can see clearly that you have changed everything ! Design, photos... So you've changed the UX ! Text is important but Google takes user engagement into account, and if users are not reassured by your new design, you will never get back your positions ! In old design buttons are clearly identifiable, it's more simple to navigate, some menus are youseful like "Why choose us ?"... I think you'd better improve old design and navigation and forget the new one !
