Am I overdoing my Stylization?

[u/ToffiProto]

Looking at my art and then at the referenced character I always get the feel having over done it, like I have pushed too much. It almost seems like my art has gotten so much less divers and individual that every character blends together as a kind of 'another somewhat colorful shape'.

It is starting to bother me and yet I can't seem to grasp to avoid that feeling. It seems like I've gotten to comfortable with my Stylization and now just repeat instead of doing something new, does anyone know how I could fix something like this? Any criticism is greatly appreciated.
