It's not about the art first.
There's a very important thing in designing anything called the gestalt principle. The sum of the parts is greater than the sum of the whole. If you remove a part the compostion becomes weaker. This poster lacks cohesion. It's plug and play. Insert band name here. Place image.
As far as what's a gigposter supposed to look like, ask Jermaine. His words not mine.
I know who this Cold Play band is becuase my girlfriend is all into them , even though I can't stand then, and this poster does seem to suit them...I respect that Jermaine's exploring new territory but his thing that 'it's not supposed to look like a gigposter' that piemel posted somewhere on here REALLY negates the validity of this poster as a gigposter. It's like all about his painting and the type looks like an after thought.
