I saw this map when it was being built. THe water was deadly and the roof was only 2 blocks high, but now I see there has been a massive improvement. I noticed the sea has a lot of detail as well despite being a no go zone. Overall, I like it. GOod luck on the submission!
The map appears to be fairly solid both in the aesthetic and gameplay department. It's nothing extremely unique or outstanding, but it does very well in the areas it needs to to be an acceptable map, so I believe it to be worth a trial!
