dont apologize for anything, its great that you're smart enough put your foot down when you want to, and I dont think anyone else is going to bug you about it.
now I think they just want to argue with me :)
your art is good, it will develop and change as it does, dont worry about pushing it in any direction all at once. if you really do want to change though, look for many different kinds of influences in different styles. my favorite place to find cool stuff is threadless, and I bet if you mixed your current style with that of many other people's, you'd create something entirely your own.
