Thank you!! I'm so happy you got the swing of it, that was my ultimate goal of the tutorials :D
It's mostly shader magic haha, I can't animate so I just used a really useful shader creator (unfortunately it is paid), I then combined a lot of the different options it gives you and animated the values!
I see you also develop in Unity, so you could find the shader pack useful!
