Hello there! Good start! I think it's got the sense of design going. I also thought it needed some heavy optimization.

Your current filter renders in 7.71 seconds with the default 600x600px render scale. Optimized render times are approximately 1 second faster than the original.

Some tips: You only need 1 instance of the original pattern. In this case, the original filter contained 2 3-color gradients which generate the stripe pattern. You can remove the second one and simply reuse what's already there. This goes for any duplicate components doing the same thing.

Alpha is unnecessary for many operations here.

While this isn't a perfect optimization... that there can be a lot more done, I thought I'd just keep it to what I see doable. The rest may be something you've done on purpose.

Cheers! Hope this helps.

Maybe you just miss it.

Oops, I probably did. It's honestly an easy fix.

And i have two 3 color gradients because one of them has just slightly brighter color and this was a problem when i was using alpha.

I haven't looked too deep into that issue but I see why you had 2 3-color gradients. Although the problem should be fixed in the optimized version in the end since I'm only using 1 source material and not using alpha. Alpha can get... very specific. So be warned using alpha.
