Simple MockupsLS Graphics
Beautiful Landing Page promoting a premium product by Lstore for Sketch and Photoshop called Simple Mockups. The long-scrolling Single Page site does an excellent job showcasing the gorgeous mockups in various angles and stacked arrangements. Neat touch with the scroll progress bar in the fixed footer.
This website has unfortunately redesigned or gone offline, so I have removed the link to it. The screenshot below hopefully preserved a bit of the design for you.
