I downloaded it. And I'm not impressed. As I said before, the ship is done well; however, that's about it. Yes, you did make a small trail. But that's it. It's a
small trail. For a ship of that magnitude, the damaged land shouldn't look like someone pushed a small, light ship through a little bit of ground. A ship of that size would tear through the ground, scarring it. I mean, for Pete's sake, there's still grass there.
Now, let's talk a bit more as to why this isn't right. If it did actually push the dirt, there would be a pile of it at the front.
This is the front of the ship. There should be little, if any, open room here. It should be packed to the brim with dirt and debris. My biggest complaint with the ship is that it's too clean. There's no dirt, there's no debris.
Alright, now that the ship is more or less taken care of, let's talk about the rest of the map. It's... empty. There are buildings, yes. But they aren't built very well, and they are few and far between. The map's too big for the number and size of the buildings in it. The parkour bits you had weren't very hard either, but that's personal opinion from an experienced MC parkour runner. Also, there is little to no terraforming on this map. It seems like you found a large island and built a dome around it. It would be nice to see some shape to this place. And here is my biggest complaint with this map. Some of the content is offensive. Scratch that, a lot of the content is offensive. I feel like some of these pictures are not appropriate for this website, so I placed them in an Imgur album:

I am livid at this map. There is no reason this should be added.
