Hi @tabeku06 great job! Don´t worry if getting the anatomy right is hard at this point. Stan just wanted to show tracings in the beginning since it's an exercise that you can use as a study tool when you dive deeper into the course. The thing to take with you from this lesson is how to do an anatomy tracing.   The two things I look for in a tracing are: 1. Varying lineweight; thicker for the border of muscles and thinner for the muscle fibers. This gives clarity to the tracing 2. Fiber-lines going all the way. I want to be clear with how the fibers track so I like to draw them all the way from where they originate to where they insert, and not just indicate them floating in the middle of the muscle.  Hope this helps :)
