The lead artist on "Curse of Monkey Island" was Bill Tiller, who founded his own (now inactive) company
Autumn Moon Entertainment. AME released two games,
A Vampyre Story and
Ghost Pirates of Vooju Island, both featuring fantastic 2D backgrounds by Bill Tiller which take the style he developed for CoMI even further.
While visually gorgeous, both games lack a bit in the storytelling department, with A Vampyre Story sadly ending on a not-yet-concluded cliffhanger.
Having said that, both MI1 and MI2 look fantastic, and the SE of MI2 isn't too shabby either. Still, I wouldn't mind MI3 looking SEs (not to mention an HD update for "Curse of Monkey Island").
