These pages were done last summer at a nearby mall. The reason I'm drawing most of the people from the back or side is because I'm trying to avoid that awkward moment where the person you are drawing sees that you are drawing them. And of course the worst case scenario after that is when they come over to see how you've drawn them. This can happen so you'll need to be careful. The people around you will occasionally pick up on the fact that you are drawing but if you haven't been looking at them, they will probably leave you alone. You might even get a compliment if you're having a good day.
I haven't had a chance to get out there lately but I'm really hoping to do some more mall drawing very soon. Maybe I'll see you out there. I'll be the guy hiding behind his sketchbook. ;)
