Contour Line Shoe Drawing

My contour line drawing was not good at all in the beginning.  When you keep doing it, it gets easier with practice. My hand contour drawings were much better by the fourth or fifth try.  The hard part is not being able to pick up your pen.  Also what makes it harder is you use a pen so you can't erase it. My shoe isn't the best, but it is better than my first try.  They were right when they said practice makes perfect!
