You're improving...
A lot of things wrong, though...
1) The Speed... Slow things down! You really don't need to have something happening every three seconds. This really shows during the space battle.
2) The Zergling... I don't know why people think they look like that, but I honestly don't. I'll leave it at that.
3) The 3D... It really didn't look too good, IMO, but it didn't look horrible, so I'll give you that.
4) The Voices... You need more Voice Actors for the humans. The Protoss at least had a distinction, but you need more human voices.
Overall... Very good! Keep up the good work.
