Constantly writing! I feel empty if I'm not writing some sort of music at all times, even if it's just in my head.
What I like about Turner is that he wasn't afraid of dark colours in his pieces. Someone criticized him for his use of black, to which he answered "If there was a colour darker than black I'd use it." Very poetic.
Aah, Mantegna! His St. Sebastian gives me chills. The way the arrows weave in and out of the flesh.
