Great tutorial! Learnt some very useful production techniques and a solid deconstruction of what makes a synthwave track sound so 80s!
A few improvements to be made. Use more free VSTs and FL studio native plugins/effects to make this more accessible to the starting bedroom producer. Or at least suggest an alternative free plugin/effect that does a similar job. All the paid plugins in this tutorial cost around $200+! I couldn't master in this tutorial based on the paid plugins and specific presets you use. Also before you even move to mastering, a short section on your approach to mixing would be really helpful!
