I've gone through the same thing before. Since a lot of mental and emotional energy goes into a artwork, having it either stolen or damaged can be quite devastating. I go through drawing ruts too. Since a lot of emotional and mental energy goes into drawings, I've noticed that sometimes I go through periods where I have to give myself some time to rest and incubate ideas. I try to put time aside every day just to draw/sketch just as an exercise, simply to maintain my ability, but I save the creative energy for the next flow of inspiration that hits me.... Awesome artwork, by the way!
