" ...Interesting how those sharp peaks in the starting form yield such a nice organic mouse shape."

Yep - you have to over-exaggerate to overcome the SubD smoothing if you want ridges or more defined edges.

Takes some back-and-forth editing to get the desired result. Although, it does go quickly.

It would be nice to have a short cut key that gave a "preview" of the smoothed result, only when the key is pressed. That way you wouldn't have to "undo" each time as you iterate tweaking the underlying structure.

Would also be nice to have a symmetry mode so you're only concerned with one-half the model when editing.
