Like MarkoH01 I have to disagree, the oversized mosaics just makes it look ugly, and doesn't contribute to anything. You certainly nailed the aesthetic style, the models are a tad bit on the cheap looking side, but censoring a game like this-wanting to be a Giallo? When was the last time you've seen one censoring its content, I have seen lots in my life and can't name a single one.
Considering the history and rejection on Steam, and offering it on GOG censored-a place where people reject any form of censorship in games, when there is no reason to, your sales will not exactly be stellar.
The bottom line is, reconsider and add an option to toggle it, and allow us to see your work as it was meant to, not because you had second thoughts and decided to censor and called it an 'aesthetic choice' because if it was, it would look differently to how it actually does.
