Victor from VZA was nice enough to record me sketching a quick Spider-man drawing at Big WOW! Comicfest in San Jose. You should check out his YouTube channel called VZA Visual Zen Advocate. There are so many great artists that he recorded doing sketches. There are videos of Humberto Ramos, Jim Lee, Neal Adams, Mark Texeria, Adam Hughes and Frank Cho to name a few. You can find his work here:
