I just discovered the show/band Flight of the Conchords. It's amazing. Also, one of the leads, Jemaine Clement, has one of those faces that you just have to try drawing. His features, as described in one episode, are "too deep set to be considered classically handsome," but are quite fascinating.
So, I ended up doing an embarrassing number of attempts (many of which are not shown here). He has a really unique nose, which I think I got okay in the front view, but in the 3/4 and profile angle it's just not working.
