Poster design

Hi guys, I want a poster design completing for advert spaces above the male toilets at a football ground.

The poster has to be A3 in size and is for the website iron-bru.net- the Scunthorpe United website. Although I could probably do this myself I am my own worst critic and I'd never be 100% happy with what I create.

I am looking to play on the poster attached, changing the can to IRON-BRU rather than IRN-BRU, the colours of the can in the club colours of claret and blue and where the barr logo is '.NET'

Underneath something along the lines of 'HAVE YOUR SAY ON TODAY'S GAME' or something witty if you can think of it. I was thinking 'positivity always welcome' as many people suggest the website is too negative. Maybe do a few variations. I'm not bothered about the scribbled writing around the poster.

If added maybe something like 'the number 1 independent iron site' or similar.

I also have another poster design on similar lines, but would like this one completing first.
