In my opinion, you shouldn't blindly follow fan desires unless you want their money Of course you should read constructive criticism but opinions like "lol vocals 8 bit is better" are to be dismissed and ignored.
In any case, I feel you should music that makes you passionate. If doing "Welcome to the Real World 2" isn't what you want to do then it'll probably turn bad or, if by chance it turns good, you won't probably like it much, which is worse than your fans hating it.
I have to say I do agree with gecko about the brand issues. It'd be a smart idea to have a different artist name for different styled projects if you don't want fanbase issues
