As I delve more and more into comic book writing, I’ve come across a couple of nifty galleries of comic book art that I thought I’d share. Both are from design blog abduzeedo.com (which I highly recommend).
Super Heroes and Villains Alphabet
This comes from the online portfolio of an artist called Ankles (that’s the closest I can find to a name). It’s an excellent series. If you like the artist, check out his/her other work at http://enymy.deviantart.com/ .

Beautiful Watercolor Illustrations of Super Heroes and Villains
You don’t see a lot of comic book art in watercolor. This is a great collection.
BONUS: Warren Ellis posted a link to a few of his comic book scripts. Just click here to go to his site and download.
