I'd suggest one minor change: the thumbnail for the second to last video ("Self-healing Kubernetes at the edge: MicroK8s, Raspberry Pis and Portainer") does not really reflect the content of the video, may I ask you to switch it to the default thumbnail? Other than that, this is good enough UX-wise; feel free to change to UX+1 once you fix that.
