I've always loved how Doug Chiang depicted the Jedi his way in the concept art he produced for Episodes I & II, even after their look had been established as something much more tame.
Though I've never seen this painting labeled, my understanding is that the figure in the foreground is Obi-wan, and the figure in the background is either Dooku or Anakin. I like to think it's the latter, decked out in a black jumpsuit that foreshadows Luke's outfit in ROTJ. The remaining combatant is cropped out to the right.
