I loved the characters and I loved the art speak. I'm not artsy but I like to Google what the characters are talking about which, in this read, made me feel artsy. I even got into looking up Graffiti artists and turned me on to Banksy (the anonymous bloke across the pond) and man, do I like some of his stuff.
The characters are easy to love. It's truly funny. I found myself giggling my ass off (once out of mortification) quite a few times.
All in All: It's a wonderful light hearted read. Read it!
