Discovered a new way to feel a lot better at anyone who rattles your cage and goes off on their way ! Yep, paint them how ever you would like to. You could go completely wild with your imagination - comic, long pointed ears maybe ? or semi-realistic, or a suitable abstract...... Unrealistic colleagues could soon find themselves becoming surreal images flying over the moon - I never get annoyed any more & I feel great seeing them again with that image in my mind :)) Extreme cases have even grown pigs trotters & sprouted animal fur and horns ! Enjoy !
