Conciseness in art is essential and a refinement. The concise man makes one think; the verbose bores. Always work towards conciseness.
Edouard ManetIn a face, look for the main light and the main shadow; the rest will come naturally — it's often not important. And then you must cultivate your memory, because Nature will only provide you with references. Nature is like a warden in a lunatic asylum. It stops you from becoming banal.
Edouard Manet
