As @Nicholas mentioned, I think this is a really strong landing page so far. I think you have a really clean and efficient design. The Call to Action is clear and you’ve shared just enough information to let visitors know what the page is all about without throwing too much information at them/overwhelming them.
I am a little nitpicky when it comes to design (it’s almost a little bit like OCD to me) so something I might consider changing is the abundance of space you have under your CTA button.
Maybe an idea would be to list off some of the topics that were covered in Episode 1 here? Some key takeaways that were covered? You could always include a brief testimonial or something similar.
I would also encourage A/B testing variants of this page with different layouts/copy/colours to mix it up.
But all in all I think you’ve built a really strong page here!
