Drama is the only thing that keeps this place interesting, man.
No, this is a perfectly fine poster. Just one of those personal taste things. I've seen tons of paintings like this while at art school - this is just presented as a poster and therefore considered unique.
The whole "schtick" approach (bears, bunnies, etc) I think is a perfectly acceptable thing, I'm just not crazy about it. I see it as a personal mark by the artist to lend a little cohesiveness to his/her body of work - half in-joke, half signature. Just doesn't jibe with what I like to see in rock poster art, which is imagery tailored to the band in some way, not to the artist's portfolio.
