Jimmy, you captured the essence of Florida on your module. Some N Scale 3D printed gaters would be a great additionn to the scene. The Krylon range of cammoflage rattle can paints are something to look into for a repaint of your palm trees. You can stain or airbrush your ballest / track for a weathered look also. Just a few ideas. Model on and stay free.
Nice work!
Great job, glad i found this video.
