I have understood there is a method that separates those who can draw or those who can learn apart from those who must struggle or "study": the ability to "project". A good artist does not do construction. They don't measure or waste their time with measuring proportion or angles. The image "appears" in their mind.They look at their canvas.They "project" the mental image that "appeared" onto the canvas and they trace over it! You don't need to study or anything it's pointless Do this trick and see if it works. If not then YNGMI.
