I started the tutorial yesterday evening without hayfever, finishid it today with watering eyes, a running nose and sinus pain. So in the end, I couldn't pay so much attention to detail anymore. 
But I really wanted to finish it, because I wanted to try the combination of Luminance with Polychromos. And I'm in love with the Luminance pencils.

Realism isn't really my cup of tea - nevertheless the class was easy to follow and included a lot of helpfull tips and hints, that helped me a lot.
