Portraiture trials

I have been working on an almost life size bust of John Muir, the Yosemite environmentalist.  I am nowhere close, but I think that I have made some good progress. No stopping until he looks similar enough.
The other issue...This is basically just another bearded guy, and I can not count on the audience knowing who John Muir is.  So while considering that, I am in the middle of deciding what other elements to include in this bust. I feel like it needs to be ironic by incorporating an element of modernity, but want to make sure that I an communicating a feeling of respect and reverence towards John. I have some work to do.

one week in with the small maquette peeking over Johns shoulder

More fussing...taller torso

This is the most pleasing angle for me.
