Hope you don't mind the unsolicited feedback -

ComfyUI-inspired node graphs are the wrong approach for visual media. Nodes are great for the 1% of artists that get into it, but you really need to build the Adobe / Figma of image and video tools. Not Unreal Engine Blueprint / ComfyUI spaghetti.

ShaderToy and TouchDesigner and Comfy are neat toys, but they're not what the majority of people will use.

We want to mold ideas like clay.

Watch the demos Adobe just gave from their conference two weeks ago. That's what you should build. Something artists and designers and creatives intuit as an extension of themselves. Not a mathematical abacus.
