It mostly works well on mobile, but the layout results in hilariously big images on desktop.
The top unit could benefit from scaling to the viewport height. Right now the grey section is 100% the height of the viewport, meaning that scrolling is not an obvious interaction. Having some yellow and text peeking up could make that more intuitive.
Not sure why you're being downvoted. The site is awful on desktop - definitely designed for mobile alone. Which seems strange - considering the target market for this.
