I have a MAC desktop with a Safari browser. When I download the images provided in the Drawing Basics course, Safari will not open the files. I am referring to the image files. Not very tech savvy - any help to open these files will be greatly appreciated.

I am a new to sketching. Looking for some advice. When I see some of the images that Stan critiques, I am thinking many of these drawings are pretty good then I look at my drawings and think wow not so good. As a beginner, is it common to be hesitant about one's drawings and being too concerned about how they look.

I am a beginner at drawing so I have decided to post the pics of the boots. Had a difficult time as you can see in my work. Right boot, I used Stan's drawing to guide me. All of the below work that has been posted looks pretty good. If any of you are a beginner like me, all I can say, you have done a good job as a newbie. Any advice for me being new to drawing will be appreciated.
