I'm trying to model this character of mine for animation and rigging: But every time I try to go about modeling her I always end up getting stuck on either her eyes, nose, or mouth. Those seem the most tricky parts for me.

I've tried spline modeling, sculpting, box modeling, point to point modeling, and even plane modeling. All with different results, but I end up getting stuck when I come across those troublesome areas no matter what.

Edit 1: I've also searched for reference images of rabbits, their topology, anatomy, and looked upon other works from other 3d artists to get an idea of what to do. I still end up stuck.

Edit 2: I changed the question into something a little less broad but will change it more if necessary, just let me know. Still new to how posting questions works on this site.

Here are some screen shots of my progress.
