I don't understand what you were trying to do with the human video.  I don't think there's any situation where you'd need 36 silos, especially to the exclusion of anything else.  I'm not sure if you noticed, but you actually blocked off one of your factories completely with the silos.  I really just don't know what you were trying to accomplish with that setup.  I noticed you stalled your economy very early into the match, and throughout the video you had a lot of excess catalyst.  It seemed like any extra you had you tried to put into storing more rather than producing units to fight with.  Also, you didn't defend your alpha and sent it out mostly alone.

The goo video you built artillery and anti-air almost exclusively.  You almost didn't mention any other unit at all, aside from the purger and mother goos.  I saw you build two radiants and two destructors, but you seemed to almost forget they were there.  There's not a lot to comment on with this video because there really wasn't much you did.

The beta guide was probably the best, but I wouldn't say that means it's good.  It was very difficult to watch due to the extremely low gamma.  The terrain was pure black and units were very dark and difficult to distinguish.  You also kept calling them the goo, rather than calling them the beta.  I don't really understand your method for building walls.  They're meant to block access to part of the map or a pathway, like you did with the wall in your human video.  You seem to be using them along the borders of the terrain instead, though it was difficult to tell for sure due to the previously mentioned gamma issues.  I also noticed you continuously stalling your economy throughout the video.
