Battle Arena Finished - Showcase

To showcase my battle arena I imported it into unity. The process of doing this requires me to apply all of the textures I made to materials in unity. This is a lengthy process and required me to adjust the textures in Photoshop as I went along. I made the normal maps at this stage because it was easier to see what they would look like in Unity than in Maya.
At first I intended to have the sun casting shadows across the map but changed my mind because it didn't feel very atmospheric. So I made it night time and added height fog to the world. I animated a camera to do a fly through of the map but it still felt like it was missing something. That's when I decided to add particles systems and some lights. There aren't many lights but they make the world look like it had been inhabited. I added a duststorm particle system and altered the colour of it which gives the illusion of wind moving the fog. Then I added fire systems to the major impact points of the alien bombing ships. This really adds atmosphere to the map.
Here is a screenshot of the scene in unity.

Overall I am really happy with my battle arena. In future I will make my models with a slightly higher poly count because these ones are very low poly and you can get more detail if you use more.
Here is a shot of the final build in unity.
