Started building this in Minecraft, does it look good

Yes

i like the entrance. Maybe try adding a tree and/or food farm, water source, and shelter with furnaces and a bed to make it self sustainable.

I already have a house on the surface
This is just a screenshot of my bridges I'm building in a cave

I would suggest using lanterns, they're fancier.

Budget.

Ikr

it looks amazing

Noice :3
