How do you talk to people at conventions or workshops?

If you want to make the most of it - maybe try asking specific questions? If you like the designs - ask about inspiration, technique or whatever it is that you're curious about. I know that for myself - when I met people I looked up to, I was pretty silent and stressed. But they are humans after all, even if their level is godlike. :3
So my advice is not to beat about the bush, but (politely, of course) ask. Every artist went through the basic level, so they probably will understand reply to the most "obvious" questions. You're risking nothing - don't be shy! :)
