Abstract Signature Tutorial Request

[Tendou]

I've seen some cool abstract signatures which look so cooooool.

And I want to know how to do that.

I've searched for tutorials for signatures like that for Paint.NET but to no avail.

There is a good abstract tutorial from MadJik which could be used to make a signature.

[Tendou]

For signatures with renders.

Not just the image.

I know I can paste the render on the abstract stuff I make from the tutorial.

But is there a tutorial specially for making abstract signature with renders?
