Here some drawing exercices used during my classes. This drawings are done by me right in front of my students during the lessons. During the first stage the point is to set up a good fundation. That means improve your stroke, control it.
One of the best tips I learned from is that when you start drawing the best way is repetition. You do not have to understand where those lines are going or what they mean. Don’t think about the design, just copy what you have in front of you: straight lines and proportion.
Please, send me your drawings and I’ll try to get a word on it!
