My first serious build, thoughts?

For context, I've never built anything to look nice, I only build it to be functional. This has been the case for both survival and creative my entire life. That being said, I wanted to give serious building a try and I think I did pretty good for my first genuine build. I'm just looking for feedback on my build and if there's anything that could be improved.

By the way, the mountains in the background being all blown up is intentional. They used to take up a bunch more space, so I blew them up to give myself more space. I started terraforming a little section but gave up and built this, so just try and ignore it😅

Also ignore the sheep getting murdered in the beginning😭
