Rabbit Girl Retopo

Hello there, this is my first time doing retopology and the project I’m working on is an anthropomorphic rabbit girl. It’s not nearly finished yet but retopology is a tad hard for me to understand right now.

Here is the front, 3/4, and right side views of it so far:

I would also like to point out I was trying to follow this as a reference here:
I was trying to go with the natural flow of the sternum, clavicle, trapezius and the sternocleidomastoid muscle landmarks.
Now I’m not sure what I like about it or what I should do to continue on.

The head physiology of a rabbit is quite different from than of a human, so you won’t really know if you got the flow right until you try to move the mouth parts, wiggle the ears, etc.

So I guess just making a temporary rig would help me decide on if its good?

I can’t speak for anyone else, but I usually get a model to a somewhat finished state, then I rig it and if there are topology problems I cut the model in half and mirror it, fix the topology, then apply the mirror. The vertex groups will automatically fix themselves most of the time – one of the reasons I love Blender so much; I don’t have to redo all the left/right naming after applying the mirror.
