There are quite a few things wrong with this map that you want to change. First of all, the homes you made. Modern usually invites opportunity for unique home designs, but they honestly don't look well made. They don't really resemble modern and have an awkward design. Secondly, the terraforming, there is none. It is just a bowl shaped piece of stone, and its all symmetrical. Terraforming is a vital part of sky wars maps so please improve it. Overall it lacks a lot of detail, such as depth and a good color pallet. Just keep working on it and don't give up until you think you've given it your all. Good luck!
