Much to simple, the floor needs a pattern or something to make it more detailed, not just stone, the colors need to be in a more advanced pattern because as it is the colors are put in a square box around each other which makes it look boring and unprofessional. The bush/tree things need to be redone and there are way too many torches. This needs to be much more "random". What I mean when I say that is to make it so each part of the build looks different. Don't make everything make symmetrical. Throw in some different structures. Try to terraform. Have different levels of your build. Add many more stairs, walls, fences, slabs, whatever you want to but add depth. If this is a build submission, make it much bigger and more detailed. If it is a skywars map, add smaller islands, stick to your theme, and renovate the middle by adding what I said above.
