I know it's a bit silly to criticize something offered for free -- I'm glad it's there for those who want it! -- but I really feel like something of the original aesthetic has been lost in translation here. The before-and-afters aren't always flattering to the new version; everything is glowing orange. Darker atmospheres have become brighter.
It reminds me of the Alan Parsons quote "Audiophiles don't use their equipment to listen to your music. Audiophiles use your music to listen to their equipment"
Sorry if this doesn't add anything, I normally just vote when I feel that about a comment.
