I think this piece has been a bit too 'digitally modified' but it's given me ideas of layering and collage for my America book, if i did it by hand then it would have the aesthetics i like. I can't remember who it was by, it is from one of the many blogs and sites i've visited recently.. Note to self: reference as you go along!!
If anyone knows of practitioners who work in similar ways, let me know =)
