Much better then the first one.
I liked this one much better then the last one you did. The Zerg were very well animated, and you seem to be doing really really well. Keep up the good work. :)
Issues:
Raynors face could use some work.
The animation still looks kinda stiff, even though the marines don't moonwalk anymore.
In a starcraft base, nothing should be standing still. You should have everything always moving in your animation as well.
