Crazy Fast Sand Crawler

I edited my initial scene of Tatooine to take up less time of the animation as with all my scenes so far hit like 27 seconds leaving me 3 seconds for my tie fighter and final scene so this was necessary and before hand took up like 8 seconds and now only 4. But the result is a very fast sand crawler so it may be wiser to edit time out of the opening scene... I'm not sure yet.

The more I watch it the less "crazy" fast it looks, maybe just fast so maybe with some tweaking I can resolve this.
