It's interesting. When I allow myself to do very wide, sprawling lines, the result is turned out to be much less exact and correct, but surprisingly more expressive. Some people already told me about such an effect, but I didn't understand, what exactly they mean, before. Because I couldn't really do this in my usual pace. But drawing with time constraints finally helped me to sort this out.
I should try to do action scenes in such a technique. What if this will helps me a bit with my problems with them?
