The only concern I have is that on mobile, the contact button (for each location) cuts off (only slightly, though) from the view. That’s all there is to criticize Other than that, it looks and works perfect.
Even better then! May I ask where you get inspiration from?
Here’s a screenshot. The div/block/section limits how the buttons are seen. For the topmost button, the shadow cuts off and for the bottom, the bottom line cuts off.
These are minimal issues and I bet won’t cause any loss to you, but since the site is otherwise top notch and clean, my eye is caught in these too easily
Excellent design. A suggestion for the Locations section is to increase gap size a bit between the items – they look a bit crowded. And I would make the text in the Location section a tad smaller. Finally, I would shorten “Get to know the location” to “About this location” or “About this project.”
