cool sketch, you were standing in the back of the big hall? it's a lot, I think I haven't even seen all of it. So many different ideas and styles. As you mention so many sources and creative approaches. I personally do not like all the same way. But some do deeply touch me. And some of the artists I could personally meet and talk to. Yesterday I was there only for a short time accompanied by my little son (painitng action on the wall was the best thing for him). No occasion really to sketch ;-) Today I will be back in the afternoon. I d' like to sketch some more.
