I kinda think this conversation is too interesting to have buried inside of this thread.
Seems more like "ramble" material.
But no worries it formed here, so lets just play ahead.
This is quickly formulated thoughts on the subject, so anyone should feel free to point out contradictions and/or oddities that I may say.
There may be better ways to explain what I mean.
Or even points that are more relevant.
In the current era of pixel art that we have apparently formed, it is generally agreed upon that the more importance each pixel has in the piece, the more "pixel art" it is.
This theory is exemplified in Cure's pixel document.

So it could be mathematically written as:
< Resolution = > Importance / Pixel
That's all fine and good in theory and practice, very useful.
But as in this case, it can make us feel weird.
The importance of each pixel becomes so real, that it can be easy to feel that in the edit, those pixels are Decroded's pixels.
That he CLAIMED them.
They were HIS choice.
And for you to put a pixel in that space of the same RGB would somehow cheapen its importance because it was not an original choice on your part.
If that sounds crazy, well that's because it is.
It's fucking bullshit.
A massive exaggeration of Sprite Ripping.
It's one thing to have someone do an edit, and say "Ok thanks for finishing that for me!" and run off.
But just because we are pixel artists, and zoom in a lot, even a single similar pixel is somehow theft?
I have to say, no.
It isn't.
What I would do is just take the insight gained from his edit and redo it manually by hand.
If some of the pixels are the same, fine.
But likely some of the choices would be different.
Anytime you post art here looking for edits, or share it with others and ask what they think, you are implicitly accepting the possibility that your art will be influenced by thoughts that are not your own.
If less pixels = more influence, then you have to be willing to accept that as well.
