Thank you! The water took almost no time to implement since I had my animation system done when I did it. Although, I personally am not very satisfied the way it looks. In the future I want to try different techniques like bump mapping, reflection and a bit of transparency to give more of a "real" look to it, just like the shadows. But I'm willing to just leave it like this is it proves to be the more popular opinion. As for the trees, I did consider it at some point. But I found that the X shaped trees work better with the lighting system (parts of the tree can cast shadow on other parts of the same tree) and the 2D trees made the world feel very flat since the only things that are 3D right now are the trees and the buildings. And I was personally going for the 2.5D look. I like to think the trees are a constant reminder to the player that they are in a 3D space since they are so common.
