It makes a lot of sense to move the lines away from the picture, this way you kinda "force your brain" to observe and hence you'll learn better. I finally finished my tracing exercises and will start the lines from reference. Will definitley try to follow the same approach as you.
And yeah! Honestly, once I stopped trying to make the perfect, "no shaky" lines, I started to finish the drawings faster. Since this is just the base for the forms and shapes, I don't think we need to be that detailed since we will, on a later stage, worry much more about the details and cleaning up the lines, than now.
Thanks for the reply!
