I've had many people over the past year or so ask me about an archive for the sketches I post on my blog. For those of you not familiar with my work, I'm a comic book artist. Right now, I work mainly for MARVEL COMICS. I've drawn SPIDER-MAN, X-MEN, FANTASTIC FOUR and others for them. I have a web site, and my blog (that I just wrote about) is updated every MON, WED and FRIDAY. You can find it HERE: http://www.mikewieringo.com/html/Blog.htm
I don't know how much space you're allowed without subscribing... but I'll be updating pretty regularly if I can upload more than I have here now.
