Dark Knight Trilogy's Tumbler WIP Final

Hello! This is my second practice project. My goal is to get used to various modeling techniques. Thinking it would be easy because it's mostly flat surfaces, I decided to model the Dark Knight Trilogy's batmobile, The Tumbler. Nope, I was wrong lol. This took me about 3 weeks here and there (I do have to work :/ ) and it's very much still a work in progress. Here's my current result. I slapped in some asphalt and tire rubber materials. Still trying to learn Cycles rendering. Gotta say, Blender is so addicting!
