I'm an absolutely huge fan of his work on Authority: Revolution. Supposedly, his work on Manifest Eternity is brilliant, too, but I need to go and track that down.
But I think Revolution, perhaps, contained the perfect example of the 'sexy, not sexual' female character that was, as always, well drawn, in Rose Tattoo - That character, in that incarnation was all about her sex appeal and how she used it, but it was never overdone, even with the bit of fanservice that we got in her laying one on Jenny Q.
So, yeah. He's definitely one of my favourites, and someone, like JH Williams III, that should've been getting way more attention than they have.
