I made a great discovery recently thanks to a post on a fellow blogger's web site - thanks!
Illustration Magazine (which I now subscribe to) is really good, inspirational, I also managed to get some back copies, so there's a fair bit of reading matter there for me. I feel like I've been kept in the dark for so long - but no longer ;)
I'd recommend this quarterly magazine to any illustrator or illustration student.
Ruth Prickett - the editor was so helpful, answering all my emails and questions really quickly - thanks.
