Game Modeling - Final Art Test WIP

I'm having a ton of fun with this model.  It's been very challenging so far, especially the treads.  I did a bit of research on different methods for creating these.  I found out that if you're not careful you can easily bust your poly count on JUST the treads.  With that said, I found that one of the more efficient ways to model these bad boys is to keep it as low poly as possible and have the texture animated instead of the mesh itself.  An animated mesh would require them to be evenly subdivided (more polygons.)

I'm approaching 50% poly count in this screen shot.
