Create this exact compact Minecraft...

Create this exact compact Minecraft building. Small 3D dimension train hub, about 20×20×12 blocks. Circular central plaza with: - Red Team lobby on the LEFT - Blue Team lobby on the RIGHT - 4 small 3D gate structures at front, back, left and right Red Team: Use red banners, red concrete, crimson wood, red lighting and red decorations. Blue Team: Use blue banners, blue concrete, warped wood, blue lighting and blue decorations. Make the two lobbies clearly different and visually recognizable. Each gate connects to train cars 1–4. Dark stone and steampunk style with purple portals. Keep everything compact and connected. No large empty spaces, no expansion. Fully 3D, not flat, not a blueprint. No text, no NPCs. Vanilla Minecraft blocks only.
