Personally, I get pretty self conscious about my art especially for where I live. I do live in the Southern United States' Bible belt... and well when your sketchbook is primarily grotesque monsters it can get awkward very fast.
Nowadays, I just draw at home to save myself the embarrassment of having people ask to see my sketchbook. I do miss drawing in parks and while I'm on break, but it got to be a bit much when people were startled to find nudes and monsters in my sketchbook. I've uhh, had some suggest I need therapy or Jesus after viewing which oh jeez... I don't even know how to comment on that. I makes me feel awful and ashamed for my drawings.
Sometimes I feel like sketchbooks are just as personal as diaries, and that it's really quite rude to ask to see something that personal unless you know the person. At the same time, I feel awful saying "No, you can't see it." I don't know which is worse...
Plus, it doesn't help that I get super nervous when people watch me draw. ;u; Streams are fine, but real life with strangers? Oh gosh, I get so flustered!
And oh jeez, those handful of people that see you draw in public and ask you to draw them or ask you to make something pro bono. That's when I really start to panic... D:
So how do you guys feel/handle drawing in public?
