SC2 Swarm Discord
The SC2 Swarm Discord is a great resource to use alongside the website to help improve. The discord contains a community of primarily Zerg players who discuss all things StarCraft, compete in various team leagues and regularly discuss ongoing pro tournament matches. In addition to this community, one of the main reasons for the creation of the discord was to help players improve. In the Zerg discussion channel, you can ask for help with anything you have been struggling with, or any questions you have about the guides on the website. In our replay analysis channel you can post replays and have them be reviewed and analyzed by other players who will give you tips on how to improve. Finally, in the game request channel you can find other players to play practice games with.
Video Content
The two best content creators to learn from in my opinion are Lambo and PiG. Lambo focuses primarily on Zerg and competitive content, so he is generally the best go to creator to watch if you are looking to learn from video content. In addition to his twitch stream and YouTube guides, Lambo also routinely gives away replay packs to his twitch subscribers in his discord channel. These are also great to learn from and I would recommend subscribing to download and learn from these replays.
While PiG does more fun content like ICYFAR and Florencio Files, lots of his content is also good to learn from. Particularly the coaching sessions he does with lower level Zerg players is good to learn from because you can learn from mistakes that are regularly made at your level in the game and how to get better at them.

Pro Streams
Professional players are often the best to learn from, whether it is from analyzing their replays that are released from events like the WCS Circuit or watching their point of view on streams. Below are a list of Professional Zerg Streams.
