Its a pretty good map submission. However its needs a lot of improving in places. The normal minecraft vines, get rid of them, you can make your own with leaf blocks, also am not a fan of the glowstone lanterns, they just look tacky, alot of builders used that style two years ago, so I'd recommend getting rid of them. Perhaps using less stairs in the structure as it looks a bit spammy, and could be a lot smoother. Spamming stairs and slabs aren't detail, I did the exact same thing a while back. Try using patterns and supports to make the structures more realistic. I do love the layout and concept though, its very impressive, just needs work here and there. But yah good job, feel free to make another submission if you make improvements.
