Sniper war scene in Maya

In Autodesk Maya 2012 I modeled and rendered a war scene for my midterm project. This project started at the beginning of class. We began by starting to model a prop then a weapon finishing with a vehicle. The scene was the most difficult to create since I needed to make a beach scene with allot of trees but that takes tons of memory, so I decided to go with just a few. Because I am new to rendering and ran into gamma issues and color control problems I had to do some tweaks in photoshop.

This is the final render with post work in photoshop. The image below is before the fixes.
