Well I have been drawing for awhile now and want to improve my skills. I am pretty good, when I started out I copied other artist's works and now I do some originals but I need to know some good exercises to improve. I don't have the inspiration to draw for some reason, some friends say it's just some time of the year or something. I want to improve and in the future make my own mangas ( yeah some people don't like manga and think it's not art but I like it). What should I practice each day?? I don't have much time to draw cuz of school and stuff but I have a little, I already draw cubes and stuff pretty well, I draw them all the time in class ( my teachers teach ssssllloooowww). I need to improve on human anatomy and stuff but I don't have enough money for books and stuff, are there any good websites?? I also wanna improve on marker work and stuff. I mean on school projects where you draw I usually do stick figures, that's how bad it is XD please help, thanks!!
