I recently bought the Fundamental Mechanics of Design Sketching course as a means of improving my urban sketching. I have to say that the course is excellent and has really improved my confidence and ability when drawing. My lines are cleaner and more fluid and a great deal of my fear of filling a blank page has disappeared. All the videos are high quality and your descriptions and demonstrations of each element are really clear. The value in the course is in actually doing the exercises right from the beginning. It’s easy to fall into the trap of thinking that understanding the principle is enough - it isn’t. I also found great benefit in reviewing the videos again. Invariably I would find an additional subtlety that I’d missed in the first viewing. I’ve incorporated your fundamentals into a daily practice routine which only takes a few minutes and is a great warm-up. I highly recommend your course to anyone that wants to improve their sketching, the fundamentals aren’t just for designers! Please feel free to use the above for marketing. Kind regards ,Barry
