I've been reading Pop Painting by Camilla d'Errico, and it's great. I highly recommend it as a book about Pop Surrealism, and as a book for any painter. D'Errico shares a great amount of information about her technique, which combines Manga art with Renaissance blending styles. She's kinda famous for Manga-looking girls with cute animals and dripping rainbows: tentacle fans will love her.
My most recent blog post is a step-by-step on a nude study. I'm not sure if I posted the blog I did just before that, which is about composition in painting and photography. That one hasn't gotten much feedback, so I'm interested to see what readers think... you can find both at killthehero.wordpress.com
