I'm sure I've seen that picture before somewhere... but if I haven't, then its not bad (never thought I'd hear myself say that). I like the art style, it reminds me of the illustrations you get in those books by Roald Dahl.
that's a stupid picture. It would be better if it were an actual picture of Phizzyland and not a picture of a poorly-drawn person saying he survived there.
It could use a lot of work on getting rid of the nasty scan side-effects and with some better coloration. Perhaps make the guy have half his head blown off showing the skull. Perhaps a psycotic look on his face would add better to the mood of the picture as well.
