Hello hello! I've been on this survival server for a while and I want to start impressing people with my builds! I'm not to experienced with building, however, but I hope someone can give me advice on what to work on.
I feel like the front of the barn needs some more detail, it seems way to flat to me. Also switch out the glowstone for torches (its a barn, not a modern home), and change the glass for fences (again, same point). You might want to mess around with the clay pattern too, add in another color to act as if the area has been worn a bit, maybe brown or a lighter color (not yellow or orange). Overall it's a good build, and if I was you I'd add in a massive field of wheat or another crop, and have a largish area to put all the livestock. Hope this helps man!
