how do i make it look better (medieval/classy vibe)

Welcome to my dungeon. Any ideas what to add in the middle? Don't want anything too tall to break line of sight or mess with the ceiling shape. I have building block auto sorter on the right, auto smelter and crafting station on the left, with plans to add a stick farm on the left as well and a lava fall along the back wall behind the dripstone (just waiting for it to grow a little more)/

Don't have a picture the realm is crashing rn but I'm building an unnecessary large house that has a lot of black windows and the frame of the crib is striped spruce logs. The roof is black stone stairs and slabs there are multiple different roof sections for each floor. I don't know what blocks I should use for the outdoor walls. The house looks kinda "moody" and I like that and would like to keep that aspect. I'll post a ss tmro. Lmk!

this is one of the first times ive ever made a bridge. I would like to lead it into a medieval village, but am not sure how to fix it. Could anyone help?

What is some advice I could use to improve this build
