Thank you for your post and showing off your work. You are clearly very inspired by visual effects and I would urge you to keep going and look at what others have made on this site. There’s a whole trove of inspiration from masters of the craft.
I would urge you to look at more reference for the type of effects you’re trying to achieve and definitely look into working with shaders more. You don’t need to write your own shaders, Shader Forge is amazing for exactly this kind of stuff.
If there’s any help you need or advice, this site is full of amazing helpful people.
