Gold/Platinum Zerg in need of assistance.

  (Edited: )

Hello guys, I am a Zerg player who is on the borderline between Gold and Platinum leagues. I really want to improve and thought if i posted here with some replays you could help me too.

Hopefully those links can help you but if any of the links (or all of them) aren't working tell me and i'll try to fix it.

Also I just randomly chose 6 replays from my unsaved games so if they aren't useful I apologize. 

ALL ADVICE WANTED AND WELCOME.

Many thanks in advance
