Crazy hair looks good, if overt. Beats having no picture at all, anyway!
As for extras, a large pocket watch would be good. He looks too much like the Sharp Guy, too... modern. The narrow tie also doesn't fit the crazy beard, some sort of XIX century tie-cloth would look better (or no tie at all, just all buttoned-up). Three-piece suit would be the best
Wizard hats? That's ceremonial dress, much outdated
Masonry symbol? Why yes, they're freemasons.
