I'm not very fond of this design. There is a unfortunate lack of text, and the design isn't all that great either.  The constant repetition of the bottles and skulls is far to monotonous and takes away from the general information and the name of the band. I like how the colors work together to create a mad scientist vibe.  It might look better if the black and the white were flipped so that the background is black and the skulls are white. The text for the headliner looks fine but there seems to be a stray skull and crossbones underneath the "e".  I think it is intentional, but it just ends up looking like a mistake.
I don't like how the text is trapped in a sea of skulls and bottles, and the general information is barely visible down in the lower right hand corner, and seems to be shrinking back.  The font has very little room to breathe.  Despite this posters horrible design, there are so many ways to make it look awesome.  Instead of using so many skulls and bottles, you could take one of each and enlarge them to fit the page or bleed off the page.  This would allow breathing room for the text.  With some work this poster could be pretty good.
