Excellent.
The ONLY con I can possibly find in this is the Voice Acting, maybe it's just how Russians speak but it almost seemed emotionless at times even when people were really angry. Plus I could tell you VA'd most of them because they all sounded the same.
That's about the only thing I could think of improving, everything else is perfect. Music fit pretty okay, Graphics and Animation (Lip Sync was awesome) were all great.
I loved it :)
