Arched Peak with waterway

Introducing the second structure of the series. Comes with an archway at the top and tunnel through as was named in the title.

Still gotta work on not making builds not so top heavy or look like they're pooling at the bottom but eventually get there. Like how the archway looks at the top and enjoying the noise painter tool when blending block types together on a surface. Just need litematica to start working for when I paste into a world and for some reason doesn't want to paste even in water despite being toggled to ignore said water smh.
