Your father immortalized in splines!
On the ears... Those are a challenge. When I was trying to do ears for my Al Capone head I started out by just making the splines along the obvious contours an peaks and valleys, even if they didn't link up.
For example there's an obvious contour running from the front, over the top and down the back of the rim to the ear lobe. And another one just side that that makes the inside of that curled edge. Eventually I had what looked like a contour map of the ear. Not every spline was a complete loop, some just outlined a particular bump and stopped.
Then I experimented with running splines across those contour lines to fill in the patches. Eventually i got an ear.
You can also do a simple dish for an ear. That's all Pixar does now, they don't even bother with ear holes.
