Rebuilding Engine from OpenGL to Vulkan, Demo's?

Hi, I’m in the process of rebuilding my portals based engine from OpenGL to Vulkan.
Is there any superior demo’s available than Sascha Willems?

No, Sascha Willems’ demos are the best I know of at the moment.

Yes, seem good though daunting at first but once you read a book about Vulkan it get’s easier, some say Vulkan isn’t for everyone but once you understand the basics I personally think it’s easier than OpenGL as it has a good feel to the layout.

Here’s a screenshot of my portals engine I’m rebuilding to Vulkan:

And here’s an early video:
