I don't see it as ugly at all. And I loved all your reflection about this intervention by Nelson Domínguez. I think he didn't sign it because he respected the original author.
That's a lesson in humility and a much more powerful teaching, working together. Creating together, instead of sitting around watching something unfinished.
This is just my perspective, it doesn't have to be the right one.

You are absolutely right, the way you justify his actions is much more coherent with Nelson's personality, he is a great artist with an incredible humility. Thanks for taking a few minutes to read and comment.
