If it's the real reason than go for it when you will feel like to. It's important that your work will appeal you in the first place, there is no need to force yourself out of your boundaries just because a group of people tells you that the actual one resembles another person art (btw, your version improves the "original" imho, as i already stated before) and in the same way ignore who will cry for keep her as she appears now for whatever reason. Do your game, if it's good people will like the MC anyways don't worry, character design is only a single part of the whole package and won't turn a 5 star game in a 1 star failure by itself. Gamers feedback could be vital for gameplay choices and things like that (especially when those are unanimous) but don't take them too seriously when they are about design or kinks you may want to include in future because everybody here has their own preferences and in the end is more important that your game appeals to you and not a bunch of random f95 users.
That said i would venture to suggest to consider some kind of "IP shading", we know what happened to Akabur and it would be a shame to see it happening again if this game will become as good/popular (and from what we can see it have this potential). I understand that put "Hermione" in the title and direct references to HP universe may be a big thing for marketing but being some more subtle could be safer in the long run. It's your choice in the end and probably also depend on where you live and other factors that concern your private life but consider what other people are writing here and judge by yourself if you want to go fully blunt about it or as i suggested take a more safe approach.
I think that all of us just want to see this initial release to become a great game with a lot of future updates, the fact that there are already 13 pages of comments for a initial release should confirm that. Just do your thing in the way you like most and you will see that it will succeed.
