My first attempt at creating a poster using Paint.net. The learning curve for this particular tool was far lesser than when I first tried using gimp. (Gimp is cool by itself. Make no mistake!) The intuitness factor was better with Paint.net.
The poster is now on my new and shiny Facebook page. Head there to have a look at it.
P.S. Thanks Vivek for the tool suggestion and thanks webtreats for the lovely grunge background.
