Learning how to draw and perfecting drawing skills is very straight forward. You simply need to draw a lot, and fail a lot until you develop an ability to truly see what you are looking at and translate that to your paper. This practice develops your aesthetic sensitivities and your technique in a range of media. I can’t stress enough how important it is for you to draw as much as possible. And, don’t worry about it being good or bad – just draw.
You also can’t work in a vacuum. Look at the drawings of your classmates this semester and use Pinterest and YouTube as a resource. I have a several Pinterest boards with examples of drawings, artwork, design and illustrations that might help inspire you to improve your drawing abilities. Search for Rusty Nelson or rlnelson55.
