Again, years of practice and learning anatomy. whether they are self taught, or they they have a teacher, makes little difference.
What about the artists who draw or paint the winners of a sporting game, on the spot?Judging from your pictures, you could use someone to show you some things.Or, what about me, I draw shit that comes out of my head, and it sure as hell didn't take "years" for me to grasp the concept. I've been doing this naturally ever since I was 4.when you look at something to draw, you studie it. whether it be for a second or 5 hours.There are even artists who have a photographic memory, and can draw right down to the tiniest pore, it's nothing to do with studying a reference point for years. Just see, and draw, or paint, or sculpt.In these pieces, I could tell you what works and what doesn't for a couple of points of view. I could even tell you how to make them better. But you would just spit out some bullshit about how art is subjective, and about how I don't know shit, and about how you are so much better than me cause you "don't have no need for no book learning (unknown comedian)," so why should I bother?
