That post you quoted wasn't really aimed at you specifically, it was more general and it's just that I have literally given the answer to those same questions at least 50, possibly a 100 times and I'm happy, when someone else steps up and saves me the typing, that's all.

Now, here then is my answer, specific to your post:

That ROTJ v1.0 was done like 4 years ago and was far less high profile at the time and I was far less experienced - I looked at the eyebrow scene again yesterday and yes, it doesn't look too great and today, I could definitely do it better, even with only those same sources but at the time, I was quite proud of it and I previewed it here before putting it into the edit and most people praised it and I don't remember anyone saying, that it would better be left as it was - because the quality of these edits was measured by a different standard then, so when you come in and start complaining about this old piece of work using such strong words as terrible or atrocious (I fail to see how that is "constructive criticism"), it's like telling a 10 year old, that that finger painting hanging in the kitchen that he made when he was four, is absolutely horrible.

If you had said it normally, without being rude about it, it would have been ok to suggest, that if some rather minor change can't be undone with high enough quality, it's better left alone (this was the case for example with the Rancor matte-lines, which I would have loved to restore but I just wasn't able to pull it off at the time) but then you went on and started suggesting, that even fixes, which were quite easy to revert should have been left in, such as reverting R2 to black (I'm not sure what you mean in the finale of IV - R2 was never recolored there) that just goes completely against the spirit of these edits - if I could pull it off, I would undo everything down to the last matte-line and the "where do you draw the line" reason for that I already explained extensively in this post.
